Symmetrical reference planes of patients' 3D facial models were constructed using three different algorithms: weighted Procrustes analysis (WPA), Procrustes analysis (PA) based on the ontology-mirror correlation method, and iterative closest point (ICP). The SRP defined by an associate chief physician served as the control (true-value group). The angular errors between each algorithm group and the true-value group were compared. The optimal algorithm was selected and combined with a three-dimensional digital smile design (DSD) to create virtual patients, followed by designing anterior restorations. The visual analogue scale (VAS) was used by patients to score the aesthetic restoration results of the conventional design (control group) and the algorithm-based design (algorithm group). <b>Results:</b> The angular errors of the WPA, PA, and ICP groups were 1.43°±0.66°, 1.82°±0.88°, and 4.74°±2.03° respectively, with statistically significant differences among the groups (<i>F</i>=41.10, <i>P</i><0.001). Pairwise comparisons showed that the WPA group had significantly smaller angular errors compared to the PA and ICP groups (<i>P</i><0.05). The VAS scores for aesthetic restoration were significantly higher in the algorithm group (8.09±0.74) compared to the control group (6.30±1.38) (<i>t</i>=-5.49, <i>P</i><0.001). <b>Conclusions:</b> The SRP constructed using the WPA algorithm demonstrated minimal angular error when compared to the expert-defined SRP and is considered the optimal choice in clinical practice, yielding high patient satisfaction.</p>","PeriodicalId":23965,"journal":{"name":"中华口腔医学杂志","volume":"59 12","pages":"1234-1239"},"PeriodicalIF":0.0,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142740758","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}

However, there still remain significant challenges, such as the regeneration of functional oral tissues. Therefore, new approaches are urgently needed. The oral is a complex biomechanical system where mechanics plays an essential role in the development and functioning of tissues and organs, as well as in the diagnosis and treatment of diseases. Thus, the integration of mechanics into oral disease diagnostics and therapeutics warrants greater attention. To date, the potential of mechanics in oral healthcare has not been sufficiently explored. Recent advancements in biomechanics and mechanobiology within oral medicine have underscored the growing relevance of mechanical theories, analytical methods, innovative technologies, and novel biomaterials in disease diagnosis and treatment. Therefore, this paper proposes the concept of \"Oral Mechanomedicine\" by summarizing research progress both domestically and internationally. It systematically describes the influence and mechanisms of mechanics in the etiology, progression, diagnosis, and treatment of oral diseases across four domains, i.e., oral biomechanics, oral mechanobiology, oral mechanodiagnostics, and oral mechanotherapy. Our aim is to enable more precise diagnoses, effective treatments, and comprehensive oral disease management.

Group Ⅰ: hDPSCs from human teeth were further divided into youth group (15-25 years old) and group middle-aged group (40-50 years old) according to different ages.
