Abstract

Background:  Pterygoid implants are best treatment option for atrophic maxilla. The present study aimed at determination of the position and angulation of dental implant in pterygoid region and dimensions of the pterygomaxillary area with cone beam computed tomography (CBCT). Materials & Methods: It comprised of 120 patients (males- 65, females- 55) requiring dental implants in posterior maxilla. CBCT scans of all patients were taken with Planmica CBCT machine. Virtual implant length, angulation and bone density was assessed.  Results: The mean± SD length of bone was 14.54 mm seen in 11 patients (males- 5, females- 6), 21.28 mm of bone was seen in 35 patients (males- 12, females- 23) and 23. 45 mm of bone was observed in 74 patients (males- 48, females- 26). The mean± SD antero- posterior virtual implant angulation in males was 75.20± 4.8° and in females was 74.31± 4.6°. The mean± SD bucco- lingual virtual implant angulation in males was 83.14± 3.5° in males and 81.22± 3.9° in females. The difference was non- significant (P> 0.05). In males, bone density in tuberosity region was 380± 148 and in females was 342± 115 and in pterygoid region was 714± 110 in males and 702± 131 in females. The difference was non- significant (P> 0.05). Conclusion: Pterygoid implant placement in atrophic maxillary posterior region is best option. Pterygoid region had higher bone density as compared to tuberosity region.
