Histologic and Tomographic Clinical Report with 13 Years Follow-up of Sinus Augmentation through Caldwell Luc Procedure in a Case of Chronic Sinusitis

Abstract

Aim: A case report discussing Caldwell Luc sinus augmentation as an adjunct for implant placement in the maxillary posterior and how to manage treatment with 8 year clinical histological and radiological follow up.Purpose: To evaluate the histologic and tomographic prognosis of sinus augmentation through a Caldwell Luc procedure. Materials and Methods:A patient reported with RCT treated tooth with vertical fracture in 16, and long standing sinusitis. During sinus augmentation procedure, 16 was extracted, sinus was approached through the canine fossa, sinus lining was removed and the area grafted with Mineros (Biohorizons, AL, USA), alloderm membrane was placed over the void and passed through the mucosa in a pouch to cover the extraction socket. A Biohorizons external implant 4/15 mm was placed after 8 months and it was loaded after 6 months.Results: histologic and tomographic reports show excellent uptake of graft after eight months, and complete osseointegration between implant and bone interface.Discussion: mucous lining has the property to grow itself within 4 weeks after its complete removal. This property of the lining makes procedures like caldwellluc possible in which its removal can be done, also giving relief from diseases like long standing sinusitis. Bone grafting can also be done with such procedures, enabling increased height, ultimately making implant placement possible. Conclusion:Implant placement in the maxillary molar area may be complicated due to enlargement of the maxillary sinus, crestal resorption due to periodontal issues, and resorption of the residual ridge or a combination of these factors. Osseous agumentation assists in creating a boney bed that can accommodate implant placement allowing utilization of implants in the posterior maxilla.
