Site development for anterior single implant esthetics: the dentulous site.

An inevitable loss of soft and hard tissue after tooth extraction often results in a compromised site for anterior implant esthetics. Various augmentation techniques have been advocated as corrective procedures, but these techniques are time-consuming and not always predictable. Therefore, the fundamental concept of site development for anterior single implant esthetics in the event of a failing tooth is to preserve the existing gingival and osseous tissue. This article identifies factors that affect tissue changes and describes an integration of surgical and prosthodontic approaches that can optimize the tissue maintenance in the anterior esthetic zone.

[Directly etched bridges. Experiences in 33 patients].

A study of immediately fabricated composite-etch bridges by using the crown of the extracted tooth as a pontic or by using a full-composite pontic is presented. The teeth to be replaced were to be extracted because of severe periodontal problems. The lifespan, the need for repair and possible advantages of this semi-permanent bridgework are discussed. The results indicate a favorable prognosis for this type of treatment in cases where there is a wish for postponing the insertion of removable partial dentures or extensive crown and bridgework.

Solyman Brown, a giant of dentistry and its poet laureate.

Solyman Brown 1790-1876), widely hailed by his contemporary literary establishment as the poet laureate of dentistry," was one of the visionary individuals who put dentistry on a true foundation of professionalism. He was instrumental in the formation of the first dental journal, the first national dental society, and the first dental school. He is one of the true giants in the history of American dentistry. Solyman Brown's great-great-grandson was cleaning out his father's attic and found a trunk full of original material relating to his illustrious forebear. Among the wealth of material was a notebook kept by Solyman's daughter, Augusta. Selections from it give us a rare personal insight into the type of person this significant dental historical figure was, as well as the struggles he endured in his hard life.

Swing-lock removable partial dentures.

The swing-lock removable partial denture (RPD) is a little-taught RPD concept that offers clinicians additional choices in the treatment of perplexing situations involving periodontally compromised dentitions, missing key abutments, and other clinical situations in which a conventional RPD design may not be feasible. This article reviews past and current literature concerning the swing-lock RPD and provides some clinical and laboratory considerations involving the treatment planning and fabrication of this often-useful RPD.

Influence of occlusal factors on treatment outcome: a study of 109 consecutive patients with mandibular implant-supported fixed prostheses opposing maxillary complete dentures.

PURPOSE: This study was undertaken to investigate the relationship between occlusal variables and clinical and radiologic findings as well as patient response to treatment outcome in patients with mandibular implant-supported fixed prostheses opposing maxillary complete dentures. MATERIALS AND METHODS: The study group consisted of 109 consecutive patients attending for annual control. They had received their mandibular implant-supported prostheses according to the Brånemark system on average 8 years previously (range 1 to 27 years). All patients were interviewed with standardized questions by one examiner, who also performed the clinical examination. The questions focused on the patients' opinion on masticatory and prosthetic function and problems. The clinical examination comprised occlusal and prosthetic factors and the health of the oral mucosa. RESULTS: The great majority of the patients were very satisfied with their present dental situation and masticatory function. Two thirds reported no problems with their maxillary complete dentures at all. Balanced occlusion was found bilaterally in 61%, and a further 4% had balanced function on one side. More than one third thus lacked balanced occlusion. Only about 60% had optimal occlusion, and 8% had poor occlusion according to common prosthodontic criteria. This was interpreted as a continuing impairment of the occlusion with time. The mean bone loss was 0.5 mm, according to available radiographs, for a mean observation period of 54 months. There were no or only weak correlations between the variables examined. CONCLUSION: The occlusal factors registered were of limited importance for patient satisfaction and treatment outcome recorded clinically and radiographically at follow-up examination of the actual prosthodontic rehabilitation.

A method aimed at achieving passive fit in implant prostheses: case report.

PURPOSE: The aim of this article is to describe a technique that attempts to solve titanium-related problems while affording passive fit. MATERIALS AND METHODS: The method basically involves the manufacture of a cast titanium framework fitted onto titanium machined abutments. After verifying the passive fit of the framework presoldered to the abutments, Nd-YAG laser welding is completed in the laboratory. RESULTS: The aim of the technique is to secure the following clinical benefits: (1) use of titanium, as it is the best-suited material; (2) use of high-precision machined abutments; (3) laser welding and its advantages; and (4) achievement of passive fit. CONCLUSION: The technique described is adequate to achieve passive fit in implant prostheses using titanium and laser welding.

Durability of acrylic tooth bond to polymeric denture base resins.

The effect of ageing in simulated mouth conditions on bond strength between acrylic teeth and denture base resins was evaluated. Bonding was tested in tension according to ADA specification No. 15. The data was analysed using two-way analysis of variance and Tukey test at P < 0.05. The ageing effect on bond strength became significant after six months of exposure when bonding of acrylic teeth to heat-cured and autopolymerised resins was significantly reduced, P = 0.001 and P = 0.03 respectively. The bond strength value of the autopolymerised resin to acrylic tooth after one year in test environment was half the acceptable value of 31.0 MPa suggested by the ADA specification No. 15, whereas tooth bond strength to heat-cured resin was acceptable even after one year of exposure.

Ridge augmentation with a folded acellular dermal matrix allograft: a case report.

Deformities of the dentoalveolar ridge are usually the result of developmental defects, periodontal disease, trauma, or surgical insult. Various techniques are available to correct ridge defects. In this case presentation, ridge augmentation was achieved utilizing an acellular dermal matrix allograft in lieu of an autograft. This report demonstrated an acceptable esthetic result with a significant improvement in the bucco-lingual dimension of the dental ridge. Color match was judged to be excellent. Furthermore, there was no post-surgical loss in papillae height. This case report illustrates an innovative soft tissue surgical technique for clinicians attempting to correct dentoalveolar ridge defects.

Removable partial denture design: a need to focus on hygienic principles?

PURPOSE: The purpose of this study was to critically analyze important hygienic/secondary prophylactic and biomechanical aspects of removable partial denture (RPD) design. MATERIALS AND METHODS: The literature related to traditional biomechanical design and open/hygienic design of RPDs was discussed by the authors at a 2.5-day workshop. The written report was circulated among the authors until a consensus was reached. RESULTS: There is little scientific support for most of the traditional design principles of RPDs, nor has patient satisfaction shown any correlation with design factors. However, there is evidence that an open/hygienic design is more important than biomechanical aspects for long-term oral health. The biomechanical importance of some components is questioned, e.g., indirect retention and guiding planes. Alternative connector designs that reduce risks of tissue injury are described. Direct retainers and pontics are discussed in relation to the possibilities they offer for gingival relief. CONCLUSION: Greater attention should be paid to RPD design principles that minimize the risks of tissue injury and plaque accumulation in accordance with modern concepts of preventive dentistry.

Development of gingival esthetics in the edentulous patient prior to dental implant placement using a flangeless removable prosthesis: a case report.

Development of gingival contours found in healthy natural dentitions enhances the esthetic results achieved with implant-supported fixed prostheses. However, this endeavor is frequently difficult to achieve, especially in the completely edentulous patient. Edentulous patients with optimal hard and soft tissue can be treated with a specially designed removable prosthesis that will develop gingival contours prior to implant placement. By means of a transitional complete removable prosthesis with ovate pontics and no labial flange, a natural-looking soft tissue profile can be developed prior to dental implant placement. A minimally invasive tissue punch surgical technique is used to place the implants, which are immediately restored with a 1-piece, cross-arch, provisional fixed prosthesis. This article presents the prosthodontic and surgical protocols utilized to improve the appearance of the definitive implant rehabilitation.
