AESTHETIC CORRECTION OF ANTERIOR MAXILLARY BONE DEFECTS THROUGH IMPLANT SUPPORTED ZIRCONIA CERAMIC CROWNS. A CASE REPORT

Abstract

The therapy of maxillary bone defects in the frontal area is amply disputed in the literature, due to the specific aesthetic requirements of the area, correlated with the needs of patients. Bone atrophy consecutive tooth extraction, infection, trauma or aplasia may lead to major bone defects [1]. Studies have shown that vertical bone resorption rate can vary between 11-22%, and the horizontal bone resorption can reach up to 63% at 6 months after tooth extraction [2]. The treatment solutions oscillate between bone defect augmentation or masking the bone defect by a prosthetic solution. Not always the anatomical and morphological conditions of the bone defect allow an efficient bone augmentation [3]. Maxillary anterior aesthetics depends on additional factors like gingival biotype, smiling line, the type of implant and the type of prosthetic restoration
