Effect of Three-dimensional Pre-formed Titanium Mesh in Maxillary Anterior Region

doi:10.13701/j.cnki.kqyxyj.2020.05.019

Abstract

Abstract: Objective: To analyze the clinical effects of simultaneous implantation with three-dimensional pre-formed titanium mesh in the maxillary anterior region. Methods: Thirty-five patients who received delayed maxillary anterior teeth implantation from 2016 to 2018 were divided into two groups according to the types of bone grafting: three-dimensional pre-formed titanium mesh group and traditional GBR group, with a total of 45 implants. CBCT was used to measure the changes of alveolar bone volume in the bone grafting area at different stages. The gingival tissue esthetics and implant health index were also evaluated and analyzed. Results: Comparing the difference of alveolar bone absorption (L₃) of two groups between bone grafting procedure (T₁) and definitive restoration (T₃), the three-dimensional titanium mesh group was less than (0.98±0.08 mm) L₃ in the traditional GBR group (1.51±0.14 mm). The pink esthetic score (PES) of three-dimensional titanium mesh group (10.50±0.27) was higher than that of the traditional GBR group (9.45±0.19). The probing depth (PD), the gingival index (GI), and the plaque index (PLI) of the two groups in T₃ showed no statistical difference. Conclusion: Three-dimensional pre-formed titanium mesh can provide more stable horizontal bone augmentation and better aesthetic effect for implant restoration in anterior maxilla.
