EVALUATING BONE TISSUE BIOTYPES IN THE MAXILLARY POSTERIOR REGION: A CBCT-BASED OBSERVATIONAL STUDY WITH CLINICAL CASE REPORT IN ELDERLY PATIENTS

Modern restorative dentistry relies on dental implantation as its fundamental procedure to provide functional and aesthetic solutions for patients who have lost their teeth. The success of implantation depends substantially on bone density and structural integrity which differ according to patient age and gender as well as the specific anatomical area. Preoperative planning relies heavily on Cone-beam computed tomography (CBCT) because it provides precise measurements of bone structure and density. The implantological advancements have not eliminated severe alveolar bone atrophy as a major challenge because bone grafting procedures lead to increased patient morbidity and treatment resistance. The subperiosteal implant approach shows promise yet traditional surgical approaches require invasive procedures and produce elevated complication rates. This research investigates bone density variations between genders and ages while developing contemporary digital methods for subperiosteal implant placement. A 67-year-old male patient with Cawood and Howell class VI mandibular atrophy underwent digitally planned subperiosteal implantation as presented in the clinical case. The customized implant received fabrication through CBCT and CAD/CAM design followed by 3D printing before its single-stage placement. The postoperative evaluation at six months showed that the patient regained their chewing ability and maintained healthy soft tissues without any adverse effects thus proving the technique's effectiveness. The research demonstrates why bone density evaluation must be tailored to individual gender needs during implant planning and shows how digital subperiosteal implantation represents a revolutionary technique for treating atrophic cases. The developed solutions match the increasing need for individualized minimally invasive dental rehabilitation
