Reconstruction of an atrophic edentulous maxilla with unilateral cleft lip and palate (UCLP) using sub-antral augmentation and osseointegrated implants: case report and 3-year follow-up

With the current sophisticated, multidisciplinary approach to the treatment of cleft palate, it is anticipated that most patients with this deformity will enjoy good dental health and function. However, due to the number of older adults who were not treated with primary bone grafting and orthodontic therapy, there remains a significant number of potential candidates who may benefit from dental implants and implant-supported prostheses. Although it was not necessary in this case, a pharyngeal extension may be added to the maxillary denture to further improve speech and deglutition. This case report presents a three-year follow-up of a complex reconstruction of a highly compromised, edentulous patient. Stable fixation of the maxillary prosthesis results in a complete return to function in an individual for whom traditional dental prosthetics had resulted in ten years of failure and frustration. Combining the disciplines of reconstructive surgery and implant prosthetics enables the clinician to achieve a predictable result (Figures 12 and 13). While this case represents an extreme example, there are millions of patients for whom implant dentistry can provide life-changing benefits.
