Color change of newly developed esthetic restorative material immersed in food-simulating solutions.

Recently, an esthetic tooth coating material has been developed. The material consisted of a primer solution, a base coat, and a top coat. The purpose of this study, therefore, was to evaluate the color change of this tooth coating material and two resin composites after immersion in food-simulating, staining solutions. To this end, the newly developed coating material with and without its top coat, a flowable resin composite, and a hybrid resin composite were employed for the evaluation. The specimens were subjected to an experimental 24-hour staining cycle: 7-hour immersion in coffee, green tea or red wine, then 17-hour immersion in artificial saliva solution containing 0.3% mucin. After 24 hours, 3 days, 1, 2, and 4 weeks of immersion, the color changes of all specimen surfaces were measured. Compared with the other materials, the deltaE* value of coating material without its top coat tended to increase as the immersion period increased until 4 weeks. On the other hand, the deltaE* value of coating material with its top coat measured the lowest among the materials tested. Based on the results obtained, it was concluded that when using this recently developed tooth coating material in dental clinics, its top coat should be properly applied.

Functional and esthetic outcome enhancement of periodontal surgery by application of plastic surgery principles.

The closure of surgical wounds in a layer-by-layer fashion, a common principle of plastic surgery, is applied in this article to the field of periodontal surgery with the introduction of a new flap design. The suggested technique is indicated with all periodontal procedures that aim for hard and soft tissue augmentation (guided bone regeneration, mucogingival surgery, or plastic periodontal surgery) where passive, tension-free wound closure is fundamental for wound healing and a successful functional and esthetic outcome. By means of a series of incisions, buccal and lingual flaps are split several times; this results in a double-partial thickness flap and a coronally positioned palatal sliding flap, respectively. Thus, several tissue layers are obtained and the passive advancement of flaps becomes possible for the coverage of augmented areas. Wound closure with microsurgical suture material is accomplished in a multilayer approach, which ensures adaptation and closure of the outer tissue layers without any tension. Two case reports demonstrate the new plastic periodontal approach.

Esthetic restoration of a single-tooth dental implant using a subepithelial connective tissue graft: a case report with 3-year follow-up.

This case report describes the use of a subepithelial connective tissue graft to restore the gingival papillae and augment ridge soft tissues adjacent to a dental implant. The patient was referred for periodontic and prosthodontic evaluation after the placement of an implant--with the implant head 6.5 mm below the adjacent cementoenamel junction--in an area of inadequate bone volume with deficient interproximal papillae and ridge soft tissues. The resulting esthetic defect was restored by means of a combined technique that used a subepithelial connective tissue graft and an emergence profile-contoured crown. A 3-year clinical follow-up with complete regeneration of the gingival papillae is described.

Interdisciplinary management of a common esthetic complaint.

Esthetic restoration of the maxillary anterior dentition often requires an integrated perio-restorative team approach. Careful attention to treatment planning and treatment sequencing is essential in ensuring a desirable outcome and a satisfied patient. Detailed measurements, diagnostic wax-ups, surgical mock-ups, and stents all are effective communication tools which can be used to enhance interdisciplinary communication. These concepts and treatment modalities are illustrated in this case report.

Surgical crown-lengthening procedure to enhance esthetics.

This article presents the rationale for the use of a preprosthetic surgical crown-lengthening procedure, particularly in the anterior region where esthetics is of great concern. Clinical cases illustrate the procedure and demonstrate how it can be used to provide enough sound tooth structure to restore teeth without impingement on the biologic width, at the same time reducing a "gingival smile" and creating new papillae.

[The importance of early surgery in preventing the esthetic sequelae of cervicofacial mucocutaneous hemangiomas in children].

Infants with cutaneous hemangiomas are classically managed medically, well-defined surgery being planned for esthetic correction at the age of 8 to 10 years. We present a series of 65 cases of early surgery in children with head and neck cutaneous or mucosal hemangiomas where irreversible and unesthetic scars were predictable. The surgical procedure was simple and the cosmetic result was better than could be expected after late surgery, limiting psychological consequences. In our opinion, the abstention rule should be changed. A multidisciplinary check-up at 2 years to identify cases with a predictably unesthetic scar after complete resolution of the angioma would help select cases where early surgical correction, taking advantage of the exceptional quality of skin in these young children, would be most beneficial.

Development of gingival esthetics in the edentulous patient with immediately loaded, single-stage, implant-supported fixed prostheses: a clinical report.

Many clinicians have reported on the success of immediately loaded implants supporting a bilaterally stabilized provisional fixed prosthesis. This protocol offers several advantages, including increased masticatory function, minimized uncontrolled transmucosal loading through cross-arch stabilization, improvement of psychologic well-being, and reduction in treatment time. However, the development and maintenance of proper dentogingival esthetics in the edentulous maxilla presents substantial challenges for the implant team. This article presents the specific pretreatment diagnostic requirements for immediate loading of single-stage implants and demonstrates a new surgical technique, followed by appropriate prosthodontic management, to develop an optimal gingival profile with interdental papillae surrounding a natural-looking dentition. One hundred fifty-one ITI implants were placed into 22 dental arches and immediately loaded with a 1-piece fixed prosthesis. The results of this technique over the last 5 years are presented.

Clinical and radiographic assessment of Class II esthetic restorations in primary molars.

PURPOSE: The aim of the study was to access the clinical performance of two esthetic materials (Vitremer and Z100 + Scotchbond Multipurpose) when used as Class II restorations in primary molars, and compare them to amalgam controls. METHODS: A total of 102 restorations were placed in primary molars of 29 schoolchildren; 40 were of Vitremer, 38 of Z100 + Scotchbond Multipurpose, and 24 of amalgam (Dispersalloy). The restorations were evaluated clinically at baseline and after 6, 12, 18, 24 months, or until tooth exfoliation or patient drop-out, following the modified Cvar and Ryge criteria. Radiographs were taken at yearly intervals, and the radiograph of the last examination available was assessed and scored. RESULTS: The majority of the restorations examined clinically up to 18 months was good (Alpha according to Cvar and Ryge), and no statistically significant differences between the groups was observed. However, at the 19-24 months evaluation, Z100 rated better than Vitremer for surface appearance and color match. The prevalence of radiolucent defects at the cervical margin for the Z100 (47%) was significantly higher than for amalgam (11%) restorations (P = 0.002) and for Vitremer (13%) restorations (P = 0.008). CONCLUSION: The three materials evaluated (Vitremer, Z100 and Dispersalloy) presented satisfactory clinical performance during the time evaluated (approximately 2 years). Approximately half of the composite resin restorations presented radiographic defects that might require replacement at a later date. In contrast, glass ionomer and amalgam restorations presented significantly less radiographic defects at the time of the final examination. This study suggests that composite resins are indicated for classII restorations in primary molars that are expected to exfoliate within two years.

Esthetic analysis of the cervicofacial region.

For many patients the primary motivating factor for orthognathic surgery is improvement of their facial appearance. In order to achieve a satisfactory esthetic result and satisfy the patients' concerns, a systematic, thorough evaluation should be performed. Because the face is a complex anatomic unit, it is best to evaluate each distinct region of the face separately, taking care to relate the various parts to the whole. During this examination it is important that the patient be in natural head position with the lips in repose and the teeth lightly touching in a centric relationship. Direct measurements from the patient are always more accurate than those obtained from photographs or radiographs. The surgeon should keep in mind that the proper relationships between the various regions of the face are more important than specific angles or numbers.

Development of gingival esthetics in the terminal dentition patient prior to dental implant placement using a full-arch transitional fixed prosthesis: a case report.

Despite significant advances in dental therapeutics, there are patients for whom no reasonable treatment is available that will reliably restore or maintain their existing dentition. The causes of future edentulism include advanced caries, failing root canal therapy, inadequate numbers of teeth to support a fixed prosthesis, untreatable periodontal disease, or a history of failed previous rehabilitations. For these patients, dental implants may provide a more predictable future than retention of their remaining teeth. It is proposed that transitional fixed prostheses designed specifically for a patient with terminal dentition offer the advantage of maintenance and development of proper gingival esthetics with improved function. Prior to implant placement, the gingival frame is established, enhancing the overall appearance of the final, full-arch implant rehabilitation. The specific prosthodontic and surgical techniques required for successful treatment of these patients are presented.

Esthetic option for the implant-supported single-tooth restoration -- treatment sequence with a ceramic abutment.

A single implant-supported restoration is one treatment alternative to consider for the replacement of a missing tooth. Technological advances in materials and machining have led to the development of a densely sintered aluminum oxide ceramic abutment, designed and machined using CAD/CAM technology. This manufacturing method improves management of the subgingival depth of the crown/abutment interface and enhances the esthetic qualities of the restoration. However, since this ceramic abutment has less mechanical resistance than metal abutments, its use should be confined to the restoration of incisors and premolars not subjected to excessive occlusal forces.

Esthetic prostheses in minor and major upper limb amputations.

In summary, the impact and value of esthetic prostheses on amputee rehabilitation and their long-term use were demonstrated in this study to have no correlation with the severity of injury and level of amputation. All patients with traumatic amputation should be given equal opportunity to receive prostheses if the service is readily available. Whether use of prostheses is temporary or long-term, they help patients cope with the traumatic life experience of limb loss.
