Digitally guided tunnel soft tissue augmentation combined with temporary restoration contouring for pink esthetic reconstruction in multiple anterior teeth:a case report
摘要
Abstract
The loss of multiple consecutive anterior teeth frequently results in horizontal and vertical alveolar ridge resorption accompanied by soft tissue collapse,presenting formidable challenges for implant rehabilitation.Achieving ideal"pink esthetics"in the anterior esthetic zone represents a significant clinical difficulty.This case report describes an orchestrated multistage protocol for managing a patient with multiple missing maxillary anterior teeth.The first-stage surgical procedure employed digitally guided implant placement in conjunction with guided bone regeneration(GBR)to restore labial bone volume.During the second-stage procedure,a tunnel technique combined with connective tissue grafting was implemented to augment soft tissue thickness and optimize tissue architecture.Subsequently,an implant-supported provisional restoration,fabricated from a nanoceramic resin composite material,was utilized for progressive emergence profile conditioning,thereby establishing a harmonious and voluminous peri-implant soft tissue morphology.This multistage coordinated implant treatment ultimately achieved natural contours and harmoniously blended color comparable to those of natural teeth,resulting in optimal pink-and-white esthetic outcomes.This integrated treatment paradigm combines surgical augmentation with provisional restoration-guided gingival contouring:the tunnel technique provides minimally invasive precision in enhancing soft tissue profile and dimensional thickness,while the nanoceramic resin composite demonstrates excellent stability and adjustability characteristics,facilitating gradual gingival architecture maturation.This clinical protocol establishes a predictable and reliable treatment strategy for complex soft tissue management in anterior esthetic zone cases.关键词
