INTRODUCTION: Tooth replacement with dental implants has proven to be a reliable and effective means of restoring the dentition. The use of implant can conserve sound tooth by reducing the need to prepare adjacent teeth as abutment. Owing to mechanical and anatomic difficulties, implant treatment in the posterior maxilla represents a challenge due to several factors such as: type of bone, bone density and pneumatization of maxillary sinus.
OBJECTIVES: to evaluate the delayed placement of basal dental implants in the posterior maxillary region.
MATERIALS AND METHODS: The research conducted on 14 patients with missing maxillary posterior teeth. Panoramic x-ray together with Cone Beam Computed Tomography (CBCT) were done preoperatively before placement of the basal dental implants. Stability of the implants were measured by periotest immediately, 1 month postoperatively and 3months postoperatively and CBCT were done immediately following implants insertion and after 3 months.
RESULTS: There was a statistically significant increase in the implant stability readings using periotest at one month and 3 months postoperatively and The mean bone density showed a statistically significant difference between immediate postoperative and at 3month
CONCLUSIONS: The use of Basal dental implants in atrophic posterior maxilla provides clinicians with a more conservative option of the treatment and help to minimize treatment duration, cost and trauma.
