Esthetic considerations in orthodontic treatment of adults.

Improvement in appearance is the primary reason that adults seek orthodontic care. Proper recognition of the dental and facial esthetic defects at the outset of treatment is the most important key to esthetic success and is, therefore, essential to satisfying the patients' needs. Division of the face and dentition into separate dimensions (transverse, vertical, anteroposterior) can be a useful way of systematically breaking down a complex problem into its component parts so that the optimal treatment plan can be developed for a given patient. For the adult patient, optimizing treatment involves a multidisciplinary team, including the orthodontist and general dentist and possibly an oral surgeon, a periodontist, and an endodontist. Proper coordination of treatment and communication between team members makes the difference between success and failure when ideal esthetics are the goal. Involvement of the patient in selection of alternate treatment plans will be essential to his or her satisfaction.

[Skin lesions in epidemic Kaposi's sarcoma (AIDS): local control assessment and esthetic results of a schedule of superficial radiotherapy].

This prospective study was undertaken to evaluate the clinical response of 51 cutaneous lesions of epidemic Kaposi sarcoma in patients with AIDS (EKS/AIDS), obtained with the use of a scheme of superficial radiotherapy (3 Gy/fraction, three fractions weekly up to a total dose of 30 Gy). The mean follow-up time was 9.3 months and the mean time to progression of EKS/AIDS disease was 7-8 months. The initial clinical parameters (pain, size, edema, and esthetics) of each cutaneous lesion were compared with those obtained after one week, one month and three months of therapy. An objective pain improvement was observed in 72% of early lesions and with statistic significance (after one week p = 0.003). After one month of therapy a decrease in lesion size, edema, and esthetic improvement was observed in 78%, 71% and 77%, respectively. Although the evolution and prognosis of EKS/AIDS remains unchanged, it indeed provided palliation, with improvement of local control and esthetics, which together with the simplicity of its application and absence of untoward effects render this radiotherapy technique a very useful indication.

Guided tissue regeneration in the esthetic zone.

Common cosmetic failures in guided tissue regeneration (GTR) procedures performed in the esthetic zone include an unacceptable postoperative recession of the gingival flap and loss of the papillae. This article describes the dynamics of flap healing that contribute to esthetic failures. Specific technique modifications of GTR procedures that enhance the predictability of successful functional and esthetic outcomes are described.

Esthetic replacement of the anterior tooth with an implant-supported restoration.

The use of implants in esthetic areas is complex because the implant must be placed in a precise location to support an esthetic restoration. This paper will focus on the treatment planning and sequencing for the restoration of single anterior teeth with implant-supported restorations. The factors necessary for a predictable esthetic outcome will be discussed.

Esthetic single-tooth replacement with implants: a team approach.

The range of indications for implant-borne prostheses in partially edentulous patients has expanded in recent years as a consequence of advances in regenerative techniques for bone and soft tissues. The esthetic demands of both patients and dentists have risen in parallel with these advances. Esthetic compromises in prostheses have become increasingly less tolerable, particularly in the anterior region of the maxilla. If the presenting situation is less than optimal, extensive preprosthetic measures may be required to prepare local tissues for acceptance of esthetically and functionally adequate prostheses. Particularly in difficult situations, collaboration by a team is recommended. The exchange of ideas and experience among specialists should begin as early as the treatment planning stage and extend over the entire course of therapy. The objective should be defined and the various steps of treatment should be coordinated with participation from all team members.

[Esthetic reconstruction of the superior hemilip using the Abbé technique modified by Burget. Apropos of 5 cases].

When a patient must undergo resection of part of the upper lip for the treatment of a cancer or following a traumatic defect of the upper hemilip, the surgeon is faced with the problem of reconstruction of a lip whose appearance and function must be as close as possible to the normal lip. The limits of the normal lip must be restored: the symmetry, equilibrium of the lips and position of the commissures must be maintained. The upper lip esthetic unit can be divided into subunits, as described by Burget and Menick. If a large part of a subunit is removed, replacement of the entire subunit rather than simple reconstruction of the defect often gives a better esthetic result (Burget). The best tissue for esthetic reconstruction of a full thickness defect of the upper lip is the lower lip. We apply Burget's principles to raise an Abbé flap, which is transferred in two stages. This approach is illustrated by 5 patients operated by this technique. Finally, this technique is compared to other techniques allowing reconstruction of the upper hemilip.

Designing the esthetic dental environment.

The esthetic dental environment requires a re-thinking of outdated concepts of office design. The design of the dental office must reflect the dentist's commitment to excellence. Each detail of the office design must be both functional and esthetic to mirror the type of work the esthetic patient expects and demands.

Vital tooth esthetics in Captek restorations.

Captek crowns and bridges employ optical effects that simulate vital tooth esthetics. The intensive red color of the blood in the vital pulp plays an important role in natural tooth appearance. This role is often ignored in restoration construction and results in a dead-looking restored tooth. To achieve optimal tooth esthetics, it is essential to mimic these often overlooked esthetic qualities.

Surgical management of ameloblastoma in the mandible: Segmental mandibulectomy and immediate reconstruction with free fibula or deep circumflex iliac artery flap (evaluation of the long-term esthetic and functional results).

PURPOSE: Ameloblastoma is responsible for 1% of all the oral and maxillomandibular cysts and tumors. It is odontogenic in origin and benign in nature but it has a high percentage of local recurrence rate and possible malignant development when treated inadequately. With the advancement of craniofacial surgical techniques, use of free flaps for mandibular reconstruction, and dental rehabilitation (such as osseointegration), the segmental mandibulectomy and immediate reconstruction with free flaps are beginning to be used more effectively for the treatment of the mandibular ameloblastoma. The aim of this article is to evaluate the clinical results of the patients with mandibular ameloblastoma who were treated with segmental mandibulectomy and immediate reconstruction with free flaps. PATIENTS AND METHODS: We present 11 patients who had segmental mandibulectomy and immediate reconstruction with free deep circumflex iliac artery or fibular flap for treatment of mandibular ameloblastoma. The average age of the patients was 25.4 years (range, 18-38 years). The patients were followed up for a mean of 29.3 months (range, 17-38 months). The functional and esthetic results were also evaluated by using a questionnaire in the long term. The questionnaire consisted of questions addressing oral continence, diet, social activities, speech, and facial appearance. RESULTS: All flaps survived totally. Recurrence was not detected during the follow-up period. It was found that all patients had good esthetic and functional results after immediate reconstruction. The social activities of patients also were not affected after treatment. CONCLUSIONS: We experienced that segmental mandibulectomy with safe borders and immediate reconstruction with free fibula flap or deep circumflex iliac artery (DCIA) flap is an ideal treatment method for mandibular ameloblastoma. The functional and esthetic results are also detected as very satisfactory for the patients.

Technique for fabricating a cement-retained single-unit implant-supported provisional restoration in the esthetic zone.

The fabrication of provisional restorations is an important stage in implant treatment. In the esthetic zone, the potential for error without the use of provisional restorations in the selection of the abutments, framework design, appropriate vertical dimension of occlusion, occlusal profile, and the esthetic interpretation may be significant. Provisional restorations are indicated in esthetic zones, for the contouring of the gingiva, to achieve an acceptable emergence profile, to have custom-guided tissue healing, and to induce appropriate soft-tissue topography. This article describes the fabrication of a provisional restoration for a single-unit implant-supported crown.

Influence of polymerization mode on flexural properties of esthetic resin luting agents.

STATEMENT OF PROBLEM: Dual-polymerized esthetic resin luting agents have become popular. However, it is not clear whether the autopolymerized versions of such products have adequate strength to meet clinical requirements. PURPOSE: The aim of this study was to investigate the effect of different polymerization modes on the flexural properties of esthetic resin luting agents. MATERIAL AND METHODS: Ten esthetic resin luting agents were studied. Materials with 3 polymerization modes (dual, auto, and light) were Appeal, Calibra, Illusion, Lute-It, and Variolink-II; those with 2 polymerization modes (dual and auto) were Bistite-II-DC, Cement-It-C&B, Clearfil-DC-Cement, Linkmax, and Nexus2-Dual-Syringe. Five flexural strength specimens (2 x 2 x 25 mm) were made for every available polymerization mode for each material. The specimens were stored in distilled water for 24 hours at 37 degrees C. The specimens were then tested for flexural strength (MPa) and flexural modulus (GPa) using the 3-point bending method on a universal material testing machine at a cross-head speed of 0.5 mm/min. Data were analyzed by Kruskal-Wallis and Mann-Whitney tests (alpha=.05). RESULTS: Flexural strength values were the highest for dual-polymerized Nexus2-Dual-Syringe (155 MPa), whereas the values were lowest for autopolymerized Bistite-II-DC (56 MPa) and light-polymerized Appeal (63 MPa). Flexural moduli values ranged from 4.3 to 10.0 GPa. The polymerization mode and luting agent influenced flexural strength and modulus significantly (P<.05). CONCLUSION: Dual-polymerized resin luting agents had higher or equal flexural strength compared to the autopolymerized mode. All the groups tested passed the flexural strength requirement of the ISO 4049 specification.

Radiotherapy and immediate two-stage breast reconstruction with a tissue expander and implant: complications and esthetic results.

PURPOSE: To report complications, failure rate, and esthetic results in patients undergoing immediate breast reconstruction with a tissue expander and implant, with or without adjuvant treatment. METHODS AND MATERIALS: We reviewed the records of the 77 patients who underwent immediate breast reconstruction with an expander/implant between January 1999 and December 2000. Complications were assessed using the Common Toxicity Criteria, version 2, scale. Esthetic results were assessed by the physician using five criteria. RESULTS: Of the 77 patients, 55 had received adjuvant radiotherapy. The median follow-up was 25 months. Complications appeared to correlate with radiotherapy (14% for nonirradiated patients; 51% for irradiated patients; p = 0.006) and adjuvant chemotherapy (54% with chemotherapy [CHT] vs. 25% without CHT; p = 0.02). Breast reconstruction failed in 21% of patients (9% of nonirradiated patients and 24% of irradiated patients; p = 0.1), and chemotherapy was associated with a worse rate of failure (34% with CHT vs. 6% without CHT, p = 0.005). Adjuvant tamoxifen, however, correlated neither with complications (45% with tamoxifen vs. 39% without; p = 0.15) nor with failure (21% with tamoxifen and 23% without, p = 0.79). Esthetic results were acceptable in 60% of cases. CONCLUSION: Immediate breast reconstruction with an expander/implant can be considered even for patients requiring adjuvant treatment. However, the complication and failure rates are three times higher after postexpander radiotherapy.

Shear peel bond strengths of esthetic orthodontic brackets.

Anecdotal reports of bracket fracture and tooth damage associated with the use of certain esthetic orthodontic brackets have been reported in the literature. With the advent of new esthetic orthodontic brackets, the need has arisen to test the claims of the manufacturers. The objectives of this study were to determine: (1) shear peel bond strengths (SPBS) of various debonded orthodontic brackets, (2) SPBS of these rebonded esthetic brackets with and without use of silane, and (3) fracture sites of all groups examined. Seventy-five noncarious human premolar teeth were randomly divided into five groups (A through E). The teeth were cleaned, stored in 70% ethyl alcohol, and mounted for testing in the Instron machine. The following brackets were bonded to the teeth with Ortho-Concise bonding resin: (A) metal brackets, (B) Silkon brackets, (C) Transcend 2000 brackets, (D) debonded Transcend 2000 brackets, and (E) debonded silanized Transcend 2000 brackets. After wet storage at 37 degrees C for 7 days, the SPBS of brackets were recorded, and fracture sites observed. There were statistically significant differences between the SPBS of metal brackets when compared with the Transcend 2000 and the Silkon brackets. These groups exhibited clinically acceptable SPBS. Debonded silanized Transcend 2000 brackets showed clinically unacceptable SPBS. Fracture sites of metal and Transcend 2000 brackets were resin-bracket, whereas Silkon brackets fracture sites were predominantly resin-enamel.

Use of the expanded skin flap in esthetic reconstruction of postburn deformity.

Tissue expansion is very useful in the restoration of postburn deformities. We describe two esthetic reconstructions of postburn deformity with expanded skin flaps. In case No. 1, the patient was plagued with the pigmented skin graft used for coverage of a burn ulcer on the lateral chest. The graft was completely replaced by expanded skin flaps and esthetic improvement was obtained. In case No. 2, the patient had postburn alopecia including the right hairline and sideburn. The expanded scalp free flap harvested from the contralateral side was used and an excellent result was obtained. We submit that tissue expansion is the technique of choice for esthetic reconstruction of postburn deformities.

Immediate function of Brånemark implants in the esthetic zone: a retrospective clinical study with 6 months to 4 years of follow-up.

BACKGROUND: Immediate implant function is a psychological benefit for the patient and makes a substantial reduction in treatment cost possible. Currently, immediate function using Brånemark implants has become an accepted alternative for complete-arch fixed restorations in mandibles and for overdenture support for some other screw-shaped implants. Clinical documentation is lacking for other applications. PURPOSE: The purpose of this study was to investigate a concept for immediate function of Brånemark implants supporting fixed prosthesis in the esthetic regions of the jaws. MATERIALS AND METHODS: This retrospective clinical study included 49 consecutively treated patients with 94 implants supporting 54 fixed prostheses, all in esthetically critical regions: 23 of the prostheses were bridges, 14 in maxillae and 9 in mandibles; 31 of the prostheses were crowns, 22 in maxillae and 9 in mandibles. At surgery, the implant platform was positioned above the surrounding bone level and bicortical anchorage was the goal whenever possible. The minimum insertion torque for accepting the implant for immediate function was 32 Ncm. Provisional implant-supported prostheses without occlusal contacts were delivered at time of surgery, and final prostheses with normal occlusion were delivered 5 months later. RESULTS: Eighty-five of the implants (90%) have passed the 1-year and 40 (43%) the 2-year follow-ups, respectively. Two implants failed in one patient before the 6-month follow-up, and another two implants between the 6-month and the 1-year follow-up, in two other patients, giving a cumulative survival rate of 96%. The average bone resorption was 0.8 mm after the first year as evaluated from 35 patients with readable radiographs. The failed implants were replaced after 3 to 4 months with immediate function; these were successful in all cases (not included in this study). The number of complications was small and did not differ in character from those normally encountered at implant treatment using a conventional protocol. CONCLUSIONS: The cumulative survival rate of 96% at 1 and 2 years indicates that immediate function of Brånemark implants used in the esthetic zone in both jaws can be a viable concept. All failures occurred in fresh extraction sites, and extra care is recommended to avoid situations with ongoing inflammation in these situations.

Adjacent implant-supported restorations in the esthetic zone: understanding the biology.

UNLABELLED: Traditionally, whe n considering adjacent implants in the esthetic zone, clinicians have encountered problems associated with deficient interproximal soft tissues. These discrepancies were often solved either by fabricating restorations with long interproximal contacts or by adding pink ceramics, both of which represent an esthetic compromise in today's demanding standard of care for restorative dentistry. This challenge has led to the recent introduction of scalloped implants. An understanding of the biology of wound healing of bone and soft tissue around implants and the remodeling process with implant-supported restorations allows the dental team to offer patients an alternative restorative solution consisting of combining conventional flat prosthetic table implants and scalloped implants. CLINICAL SIGNIFICANCE: This article illustrates the biologic behavior of wound healing associated with dental implants and shows a step-by-step clinical case in which a patient received four adjacent implants in the esthetic zone. It also describes key elements in laboratory communication when dealing with the aforementioned restorations.

Critical appraisal. Immediate loading of implants in the esthetic zone.

The predictability of dental implants using the traditional branemark protocol has been well documented. Since its inception, this protocol has been progressively challenged to decrease treatment time, minimize the number of surgical procedures, and maximize esthetic outcomes. Today, in specific clinical situations, implants may be placed and immediately loaded with provisional restorations. Immediate loading in the edentulous mandible has been well documented. There are also good data to show that immediate loading of the edentulous maxilla is also feasible if bone quality is suitable. The focus now has shifted toward immediate loading of implants placed in the esthetic zone. Clinicians have recognized that the challenge of providing anterior tooth replacements is in preserving the hard and soft tissue components that exist around natural teeth. The advantages of immediate restoration are obvious; however, the application of immediate or early load may pose an increased risk of implant failure in single-tooth situations. The prerequisites for achieving and maintaining acceptable results are not fully known. This review examines some of the literature concerning the reliability of early or immediate loading of implants placed in the esthetic zone.

Novel esthetic bonded retainers: a blend of art and science.

Novel esthetic S2-glass fiber-reinforced composite wires were fabricated in round (0.022 in.) and rectangular (0.021 x 0.028 in.) profiles, with flexural moduli comparable to martensitic nickel titanium and flexural strengths comparable to beta titanium wires. These wires were bonded clinically to the facial surfaces of teeth in three situations in which flexible-bonded retainers are conventionally used: the retention of a closed median diastema, the retention of space closure following premolar extraction, and the retention of a canine that had been severely malpositioned. These bonded esthetic wires were monitored clinically up to 12 months to ascertain patient's acceptance and structural integrity of the retainer. No clinically observable defects were noted during the study, and no patient described any adverse intraoral effects from the retainer's presence. In this report and on the site http://++www.clinorthodres.com/cor99-c-056, the indications for, and the present design philosophy of, flexible-bonded retainers are discussed, along with the wire properties necessary to achieve optimal stability of tooth position. In addition to demonstrating excellent esthetic characteristics, these photo-pultruded composite wires satisfy the flexural requirements necessary to achieve physiologic stability when used for flexible-bonded retention.
