Purpose:
Acrylic resin teeth on fixed implant prostheses are subject to time-dependent wear. The purpose of this retrospective analysis is to evaluate and describe the management of such wear in the context of selected variables-patient gender and age, dental arch location, and opposing dentition. The clinical and dental laboratory process to replace the worn teeth is defined as a retread.

Materials and Methods:
A retrospective database review from a single private prosthodontic practice was carried out on all patients who had undergone a retread procedure. The patient pool included 205 arches in 194 patients (70 in men, 135 in women) with a mean age of 57.4 years (range: 19.9 to 80.5 years). The retread procedure is described.

Results:
The mean time between final prosthesis delivery and retread was 7.8 years  (range: 1.1 to 22.9 years). Statistical analysis was significant according to dental arch and opposing dentition. A statistical
difference was also noted in patients undergoing multiple retread procedures, with a reduction in time between the subsequent procedures.

Conclusion:
Acrylic resin components of implant-
supported hybrid prostheses wear over time and are influenced by a combination of the nature of the opposing dentition and patient habits. The dental laboratory process to retread the implant-
supported framework is important for long-term patient care and maintenance of an appropriate vertical dimension of occlusion . lnt J Prosthodont 2016;29126-131. doi: 10.11607/r1p.4277.

PURPOSE: The purpose of this patient report is to accurately portray the clinical experience of treating an active bulimic patient by employing an immediately loaded dental implant protocol to provide the patient with an expedited esthetic and functional result. Implementation of a psychometric component statistically quantifies the psychological effects of the oral rehabilitation.

MATERIALS AND METHODS: A 34-year-old woman presented with severe dental perimolysis (erosion) resulting from a 28-year history of bulimic behaviors. Clinical and radiographic evaluation of the existing dentition indicated advanced dental erosion and previous restoration attempts in a state of failure. The patient’s existing teeth were extracted and treated with full maxillary and mandibular implant-supported prostheses, following the Teeth in a Day® (TIAD) immediate functional loading protocol. Psychometric assessment was conducted through administration of a 20-item questionnaire, as seen in previous literature.

RESULTS: Radiographic and clinical analysis suggested all implant fixtures to be viable and accompanied by normal levels of alveolar bone 7 months into treatment. Questionnaire results at the new-patient presentation (T1) resulted in a composite score of 4.0 (SD = 2.9; P = 0.004), indicating severe body-image dysphoria. At 3 months postoperative (T2), the questionnaire score was 0.4 (SD = -1.7; P = 0.09). The final psychometric questionnaire at 7 months (T3) resulted in a score of 0.5 (SD = -1.5; P = 0.12). The patient was followed for a total of 7 years following implant placement.

CONCLUSION: In this patient report, oral rehabilitation using the TIAD protocol provided an expedited and predictable alternative method for restoring functional abilities, esthetics, and self-esteem to a severely depressed bulimic patient. Psychometrically, at the postoperative (T2) and final testing period (T3), the patient’s body image profile was no longer considered to be significantly different from established normative values.
