The Study Of Ovoid Bridge Technology In The Improvement Of Gum Tissue Morphology On Surface Of Pontics

Objective Preliminary investigate the ovoid bridge technology in improving the fixed bridge in the anterior teeth of gum tissue morphology and the effect of aesthetic.Methods 1:Cases collected:Select 10 patients with maxillary anterior teeth to be extracted as the research objects;2:Make temporary crowns with ovoid bridge:The routine tooth preparation on both sides of the abutment teeth,making alginate impression, making temporary crowns outside of the mouth,extracting teeth with minimal invasion under local anesthesia,extrusing temporary crowns in place after bleeding,bonding.Visit every 2 weeks.Observing gum and inflammatory conditions;3:Three months after teeth extraction:Waiting for gum tissue morphological stability,gingival papilla and ovoid shape formation.Making silicone rubber impression and permanent restoration;4:Reviewing evaluation aesthetic effect after 6 months and 1 year, recording the following indicators:gingival index and the level height of gingival papilla.Results 1:All temporary crowns were satisfied with Gum tissue morphology;2:Wear teeth after 6 months and 1 year follow-up, good gingival margin on pontics,keeping healthy state with ovoid bridge under the mucous membrane,without inflammation and ulcers.The line of gingival margin was better.Pseudo gingival papilla were formed.3:Ten patients were satisfied with the effect.Conclusions The ovoid bridge technology to improving gum tissue morphology on surface of pontics and anterior teeth on aesthetic effect is simple and feasible.
