Focused Clinical Question What is the efficacy of a guided bone regeneration procedure, consisting of the combination of allograft particles and an absorbable collagen membrane, in horizontally augmenting alveolar bone in a healthy white patient, compared with other horizontal ridge augmentation techniques? Clinical Scenario A 20‐year‐old white female presented to the University of Iowa College of Dentistry Faculty Practice (Iowa City, Iowa) in April 2014 with a chief complaint of “I lost one of my upper front teeth and I would like to replace it.” Her medical history was non‐contributory, and she never smoked. Tooth #11 was extracted in an oral surgery practice, alongside her third molars, ≈2 years before the consultation for tooth replacement. The reason for extraction was severe tooth malposition and ankylosis. Extensive bone removal was required at the time of extraction. Intraoral examination revealed a marked horizontal ridge deficiency, which was confirmed radiographically on cone‐beam computed tomography scan analysis, necessitating bone augmentation before implant placement in an ideal restorative position.
