New drill technique may eliminate need for bone grafts in dental implants

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged 18 years or older and within the upper age limit specified in the final ethics-approved protocol. * Healed edentulous sites involving single or multiple missing teeth in the maxillary or mandibular arches. * A post-extraction healing period of at least 6 months before implant placement. * Adequate vertical bone dimensions for dental implant placement, as assessed using CBCT. * Absence of active local infection or pathological lesions at the proposed implant site. * Clinical suitability for dental implant placement and osseodensification-assisted osteotomy preparation. * Ability and willingness to provide informed consent and attend the scheduled follow-up visits. * Maintenance of acceptable oral hygiene. * Alveolar ridge width of ≤8 mm at the crestal level, measured buccolingually, and considered to require horizontal expansion during implant-site preparation. * Implant sites classified as Misch D1-D4 according to the protocol-specified bone-quality assessment. Exclusion Criteria: * Acute or chronic infection or a pathological condition at the proposed implant site. * Severe buccal plate undercut or ridge concavity that precluded safe implant-site preparation. * Insufficient vertical bone height for the planned dental implant. * Inadequate interarch distance for implant-supported rehabilitation. * Severe parafunctional habits, including clinically significant bruxism or clenching. * Heavy smoking, defined as more than 10 cigarettes per day. * Use of medications considered likely to compromise bone healing according to the approved protocol, including relevant corticosteroid or antiresorptive therapy. * Uncontrolled systemic disease or a medical condition that could materially affect surgical healing or implant treatment. * History of radiotherapy to the head and neck or chemotherapy within the preceding 5 years. * Current pregnancy at the time of the surgical procedure. * Inability or unwillingness to provide informed consent or attend the required follow-up visits
