It is a common esthetic concern that may significantly affect patients' appearance and psychological well-being. With the continuous development of minimally invasive esthetic dentistry, more precise and individualized treatment strategies have become available for the management of discolored teeth. This article systematically reviews the etiology, clinical assessment, and advances in minimally invasive esthetic restoration for tooth discoloration. A multidimensional assessment framework based on the degree of color change, the depth of color involvement, and the extent of tooth structure loss is summarized to facilitate clinical decision-making. According to the comprehensive assessment results, individualized treatment strategies, including professional cleaning, tooth bleaching, microabrasion, resin infiltration, direct composite restoration, porcelain veneers, and all-ceramic crowns, should be selected to maximize the preservation of natural tooth structure while achieving esthetic and functional rehabilitation.

Autogenous connective tissue grafting (CTG) currently has the strongest evidence base and offers a high degree of predictability for soft-tissue augmentation. It can effectively increase peri-implant mucosal thickness, improve soft-tissue conditions at sites with a thin gingival phenotype, preserve buccal contour volume, and stabilize the peri-implant mucosal margin. However, its clinical benefits are primarily confined to soft-tissue dimensions and should not be indiscriminately interpreted as providing universal protection against peri-implant marginal bone loss. Moreover, improvements in all esthetic outcome measures cannot be assumed to occur concurrently. Soft-tissue substitutes, particularly collagen matrices, avoid donor-site morbidity and therefore represent clinically valuable alternatives for cases with low-to-moderate esthetic risk and limited soft-tissue deficiencies. Nevertheless, at high-risk sites characterized by a thin gingival phenotype, a high smile line, pronounced buccal contour collapse, or planned immediate implant placement, CTG remains difficult to replace because of its superior augmentation capacity and long-term stability. Clinical decision-making should be guided by a systematic risk assessment that integrates local hard-and soft-tissue conditions, the three-dimensional position of the implant, the transmucosal contour of the prosthetic restoration, and the patient's esthetic expectations. Precise selection of the timing of augmentation, together with the appropriate surgical technique and grafting material, is essential for developing an individualized treatment strategy that balances clinical effectiveness with minimal invasiveness.</p>","PeriodicalId":23965,"journal":{"name":"中华口腔医学杂志","volume":"61 9","pages":"1251-1257"},"PeriodicalIF":0.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148867060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patients were assigned to the experimental group (<i>n</i>=19, receiving IIPP combined with a CTG harvested from the palate) or the control group (<i>n</i>=12, receiving IIPP alone) and followed up for 12 months. Cone-beam CT and intraoral scanning data were collected and standardized. Evaluation indicators included implant survival rate, complications, horizontal facial bone thickness, vertical facial bone height, vertical changes for gingival margin, vertical changes for mesial and distal papilla height, horizontal changes for facial contour, and pink esthetic score. Statistical analysis was performed. <b>Results:</b> No implant failure occurred in either group during the 12-month follow-up. Regarding bone parameters, at the implant shoulder level (0 mm), the loss of horizontal bone thickness [(1.90±1.19) mm <i>vs</i>.
