Cone-beam computed tomography evaluation of the possibility of fabrication of screw-retained implant crowns on maxillary central incisors

BACKGROUND: Immediate implant placement to the fresh socket of extracted tooth, with immediate loading, is well documented. Dental roots in proximity vestibular plate require thorough attention from clinicians. Implants placed close often lead its resorption and gingival recession. Therefore, dental surgeons place implants 23 mm away plate. In turn, prosthodontists plan so that screw channel not on surface, which most significant aesthetic area. However, this always possible, there a conflict between proper primary stability simultaneous loading screw-retained crown.
 AIM: To conduct radiological assessment ideal for MATERIALS AND METHODS: A total 120 cone-beam computed tomography (CBCT; 3 groups 40 people different root positions) were analyzed. each group, possibility extracting tooth 1.1 inserting an was evaluated compliance protocol implantation have shaft artificial crown palatal surface.
 RESULTS: Group C defined as favorable crown. The least group N. total, 40% cases located palatally, 26.6% incisal edge, 33.3% CONCLUSIONS: Careful analysis CBCT when planning implant-supported restoration area integral part treatment. team approach required planning. larger percentage cases, prosthetics maxillary central incisors involve use alternative solutions crowns.
