Osseointegrated craniofacial implants in the rehabilitation of orbital defects: an update of a retrospective experience in the United States.

STATEMENT OF PROBLEM: Since their introduction, craniofacial implants have been used in prosthetic rehabilitation of facial defects. The literature, however, indicates marked variability in outcomes using implants for the retention of orbital prostheses. PURPOSE: A multicenter report updating the experience in the United States with the use of craniofacial implants for prosthetic rehabilitation of orbital defects is presented. MATERIAL AND METHODS: Surveys were sent to clinicians at 25 centers where maxillofacial prosthetic treatment is provided to obtain retrospective data regarding patients who completed implant-retained orbital prosthetic rehabilitation. Data on implant placement location, radiation treatment history, and use of hyperbaric oxygen therapy were collected and assessed in relationship to implant survival over time. The Kaplan-Meier life table and Wilcoxon analyses (alpha = .05) were used to assess the significance of the findings. RESULTS: Ten centers responded, providing data suitable for statistical analysis on 153 implants placed to retain 44 orbital prostheses and followed for a mean period of 52.6 months. Forty-one implant integration failures occurred during this follow-up period, resulting in an overall integration survival rate of 73.2%. No significant relationship was found between radiation treatment history, hyperbaric oxygen therapy history, or implant placement location and implant survival. Individual responses revealed large variability between reporting centers in treatment outcomes. CONCLUSION: Craniofacial implants may offer marked benefits in the prosthetic rehabilitation of orbital defects when compared to conventional adhesive retention designs. However, questions remain regarding long-term predictability and the impact specific factors may have on treatment outcomes. Insufficient data is currently available from which to draw statistically meaningful conclusions. The establishment of a national database designed to acquire adequate data to assess treatment outcomes is recommended.

Lingualized occlusion: an occlusal solution for edentulous patients.

Occlusion is a critical component in any aspect of prosthodontic care including that related to the treatment of dentate, partially dentate, or edentulous patients. When complete dentures are fabricated for an edentulous patient, occlusion has a considerable influence on the outcome of treatment. Due to the relative simplicity involved in development of a lingualized occlusal scheme by dental laboratory technicians, this approach has gained favor among practitioners who are able to evaluate and/or correct tooth arrangements for complete dentures. This article will highlight the influences of a lingualized tooth arrangement in complete denture occlusion as it relates to improving edentulous patients' function and quality of life; it will also demonstrate a predictable approach to achieving lingualized occlusion in complete denture prosthodontics.

Repair of bis-acryl provisional restorations using flowable composite resin.

Provisional restorations provide interim coverage for prepared teeth while fixed definitive restorations are fabricated. Several types of autopolymerizing acrylic resins have been used for many years to fabricate provisional restorations. In recent years, bis-acryl resin composite material has gained popularity among clinicians for the direct fabrication of provisional fixed restorations. Occasionally, deficiencies may occur while fabricating a direct provisional restoration and require chairside repair. This article describes an effective procedure for the use of light-polymerized flowable composite resin for the intraoral repair of bis-acryl provisional restorations.

The use of a rotational-path design for a mandibular removable partial denture.

The lack of display of anterior metal clasps is a primary advantage of the A-P rotational-path mandibular RPD design. A disadvantage of this design is that it relies on rigidmetal guiding plates for anterior retention and stability. Loss of retention may require procedures much more involved than the simple adjustment of conventional RPD clasps. Proper adherence to design, survey, fabrication, and adjustment procedures described by the authors should result in an esthetically pleasing and well-retained tooth-supported removable prosthesis. This article recommends the A-P rotational-path mandibular RPD as a treatment the clinician can use to restore multiple missing anterior teeth and satisfy a patient's financial, esthetic, and functional requirements.

Fixed restoration of sectioned mandibular molar teeth.

A mandibular molar tooth may have its furcation area or one of its roots severely affected by periodontal disease or caries. Multiple factors must be favorable to restore health to such a compromised tooth. Adequate bone support for stabilization of the individual roots and coronal segments must be available after periodontal therapy. Root morphology and separation space must allow for ease of preparation and cleaning between the sectioned roots. Endodontic therapy should be uncomplicated and provide an excellent prognosis for long-term success. All caries must be removed and adequate tooth structure must remain after root and crown sectioning. Appropriate resistance and retention form must be achievable after tooth preparation of a sectioned mandibular molar. If these conditions can be met and the patient wants to keep the tooth, fixed restoration of a sectioned molar tooth is a viable treatment alternative to extraction and replacement with a removable partial denture or a dental implant. This article has described factors and procedures that should be considered for successful fixed prosthodontic treatment of sectioned multirooted mandibular molar teeth. The authors recommend an interdisciplinary diagnostic and treatment planning approach before performing endodontics, providing periodontal therapy, and restoring bicuspidized or hemisectioned multirooted teeth.

The use of sectional impressions and a transfer index for extensive fixed prosthodontic treatment.

The philosophy of positioning the margins of crowns supragingivally may not be applicable with the presence of caries, erosion, abfraction (noncarious cervical lesion), short clinical crown length, or esthetic concerns. In such situations, it is essential not only to record precise subgingival details of all of the prepared teeth but also to accurately transfer them to a working master cast. If a patient presents with oral and/or gingival conditions that compromise the clinician's ability to obtain a single full-arch impression for extensive fixed restorations, a technique using sectional impressions, an intraoral transfer index, and a transfer impression for transfer dies will play a vital role in the patient's treatment.

M. M. House mental classification revisited: Intersection of particular patient types and particular dentist's needs.

Fifty-three years ago, M. M. House devised a classification of patients on the basis of how they behaved in response to the prospect of becoming edentulous and on how they subsequently adapted to wearing complete dentures. Although House's system was an important contribution, it failed to consider the dentist's emotional reaction to a patient's behavior as part of an understanding of how the patient and doctor cope with the dental treatment. This article presents an expansion of the House classification to include the behavior of the dentist as a codeterminer of the patient's behavior. This expanded classification system is based on empiricism and awaits scientific validation or clinical application to determine its ultimate validity, reliability, and effectiveness.

The use of diagnostic wax-ups in treatment planning.

The use of diagnostic wax-ups as diagnostic aids in treatment planning has been presented for use in various situations--from simple patient assessment to more extensive prosthodontic rehabilitation. Requesting a diagnostic wax-up from the dental technician may add to the expense of treatment planning for a patient because of the laboratory fee incurred for this service. The cost is negligible, considering the value of identifying potential treatment obstacles that could affect both treatment outcomes and patient satisfaction.

The use of composite resin in removable prosthodontics.

Economic, esthetic, and concerns of tooth preservation are important when considering bonded composite resin for the partially edentulous patient's prosthetic rehabilitation. This article has described the clinical success of the use of bonded composite resin in removable prosthodontics. Composite resin may be used in daily clinical practice for the restoration of abutment teeth in contour, vertical support, and re-establishment of a patient's vertical dimension.

The partially edentulous patient: fixed prosthodontics or implant treatment options.

The replacement of missing teeth by conventional fixed partial dentures or by implant supported prostheses occupies a major portion of the average restorative and prosthodontic practice. New materials, techniques, and technologies are constantly being added to our armamentarium. The demand for fixed prosthodontic patient services will continue to grow. It is the ultimate duty of the provider of these services to utilize an evidence-based rationale when determining the best possible treatment for the partially edentulous patient.
