    CLINICAL AND RADIOGRAPHIC EVALUATION OF OSSEODENSIFICATION VERSUS OSTEOTOME FOR SINUS FLOOR ELEVATION IN PARTIALLY ATROPHIC MAXILLA: A PROSPECTIVE LONG TERM STUDY
    (EDJ, 2019-01) Arafat, Shereen W
    Objectives: The current study was conducted to evaluate crestal sinus floor elevation with either osteotome or osseodensification in posterior atrophic maxilla. Material & methods: 24 crestal sinus floor elevations were performed for 24 patients with at least 5mm residual bone height. 12 randomly selected patients received osteotome sinus elevation (group 1), and 12 received osseodensification sinus elevation (group 2). The treatment outcome was evaluated at 6, 12 months of healing clinically and radiographicaly. Implant 1ry and 2ry stability, marginal bone loss, and bone gain were recorded and statistically analyzed. Results: group 2 showed significantly higher ISQ values immediately postoperatively and at 6 months. There was significant increase of bone height (bone gain) in both groups (P=0.001), and bone gain was 2.79±0.30 mm and 3.33±0.25 mm in group 1 &2 respectively. Conclusion: Osseodensification sinus floor elevation was superior to osteotome elevation regarding the 1ry & 2ry stability, and bone gain.

    Reconstruction of Cranial Bone Defects Using Polyamide 12 Patient-Specific Implant: Long Term Follow Up
    (Lippincott Williams and Wilkins Ltd, 12/01/2022) Arafat, Shereen W; Ibrahim, Waleed H; AlDainy, Duaa Gawad; Salama, Dina; Shaheen, Hamed A
    The main objective of this study was to evaluate the use of patient-specific polyamide 12 implants in cranial bone defect reconstruction. Ten patients who underwent prior decompression craniectomy were selected for the current study. Skull scanning by computerized tomography was performed and used to make virtual planning of the implants to be transformed into physical implant using selective laser sintering. Cranioplasty was performed through coronal surgi- cal approach where cranial implants were fixated using 2.0-mm mini-screws, and plates. Patients follow-up was from 12 to 36 months. Glasgow Outcome Score recorded 1 (good recovery) for all patients. Patient and surgeon satisfaction for the esthetic outcome were measured using visual analog scale as mean of 10 0 and 9 1, respectively. Cranial symmetry index was calculated as mean score of 98% 1%, indicating highly accurate symmetry, and preoperative virtual planning and postoperative outcome were compared for accuracy analysis with a mean difference of 0.3197 0.1649, which indicates high accuracy. Polyamide12 cranial implants seem to offer a promising option to cranial bone reconstruction with patient-specific implants. This study ensures proper cosmetic and clinical outcome.
