Abstract
PURPOSE: Despite socket preservation and/or immediate implant placement, resorption of the buccal plate after dental extraction continues to pose esthetic challenges to clinicians. Buccal plate preservation (BPP) is a technique that has been recently proposed with an aim to reduce the incidence of such resorption. This study was conducted to assess the long-term efficacy of BPP in maintaining the thickness of the buccal cortical plate after immediate implant insertion and provisionalization. MATERIALS AND METHODS: Ten consecutive patients were included in this study. Each patient underwent extraction of a non-restorable tooth, BPPPBPP, single immediate implant placement and immediate provisionalization. Cone beam CT scans were taken 3 months after surgery (T1) and 5 years after surgery (T2) to evaluate the effectiveness and longevity of the BPPPBPP technique in maintaining the augmented bone width. Two distinct measurements were taken for bone evaluation: (a) R1: 1 mm apical to the implant platform and (b) R2: 5 mm apical to the implant platform. The long axis of the implant was used as a fixed reference. Statistical test analysis was conducted using the SPSS software. Student's t test was used to assess statistical significance, and a p value of < 0.05 was considered significant. RESULTS: There were six females and four males in the study. The mean age of the sample was 37.6 years (range 23-64 years). At T1, the mean bone thickness of the buccal plate was found to be 2.36 mm at R1 (range: 1.9-3.1), and 2.23 at R2 (range: 1.9-3). At the T2 interval, the mean thickness of the plate was 2.28 mm at R1 (range: 1.7-3) and 2.18 at R2 (range: 1.9-3). The differences in these mean values were not statistically significant. CONCLUSIONS: BPPPBPP is an effective means for augmentation and maintenance of the buccal cortical plate around an immediately placed and provisionalized dental implant. It is a viable alternative to socket preservation with the added benefit that it allows for immediate implant placement.
