Abstract

ABSTRACT
Objective: To assess the marginal bone loss in the angled implant in the posterior maxillary region.
Subjects and methods: . To evaluate marginal bone loss by CBCT after 6 month of loading
A total of 14 implants, 7 angled implants and 7 straight implants in posterior maxilla with surgical guide. seven patients ranged in age between 40.0 – 43.0 years with a mean age of 41.71 ± 1.25 years for Angulated implant group and seven patients ranged in age between 44.0 – 45.0 years with a mean age 44.43 ± 0.53 years for Straight implant group. flap less approach through surgical guide with angulation 25-30 for angled implant and straight implant without angulation.
Results: Angulated implant showed a higher significant buccal marginal bone loss than Straight implant at prosthetic and 6 months after loading. Angulated implant showed a higher significant palatal marginal bone loss than Straight implant at prosthetic and 6 months after loading.
Conclusion: the angled implant showed a higher significant marginal bone loss than the straight implant on the prosthesis and 6 months after loading. However, angulated implants can be a satisfactory alternative to vertical implants to avoid transplant procedures.
