About

This study was conducted at Ege University, School of Dentistry, Izmir, Turkey. Patients enrolled require implant placement to the atrophic posterior maxilla. Patients were treated with either the specifically designed drills or the osteotomes. The outcome variables were primary stability, marginal bone loss, implant survival, and patient-reported outcomes. The investigators aimed to compare the treatment outcomes of two different techniques used in dental implant placement with internal sinus lifting.

Full description

This prospective, randomized clinical study was conducted at the Ege University School of Dentistry and Department of Oral and Maxillofacial Surgery. Patients with atrophic maxillas and at least one tooth loss in this region were included. Randomization was performed to assign the patients to study groups. Patients treated with internal sinus lift using osteotome and implant surgery were assigned to Group 1, and patients treated with internal sinus lift using specifically designed drills and implant surgery were assigned to Group 2. At six months postoperatively, the healing cap was inserted during the second stage of surgery.

All implants were assessed based on primary stability (using implant stability quotient and torque value), marginal bone loss (as millimeters), and implant survival (as a percentage). Also, patient-reported outcomes were collected, including pain (using a visual analog scale), analgesic consumption (number of drugs taken during a week), and oral health impact profile survey).
