CBCT scans were taken preoperatively and at 1-week and 1-year follow-ups. Measurements at 1-week included interdental distances, root injuries, and periodontal detachment, while 1-year follow-up assessed endodontic treatment and osteotomy healing. Results showed no damage to the 420 roots at risk, though 38 roots had osteotomy extensions into the periodontal ligament. The mean preoperative minimum distance between roots was significantly different between sites with intact and detached periodontal ligaments (P < 0.001). One tooth required endodontic treatment at 1-year follow-up. Incomplete healing of vertical osteotomies was more frequent in female patients (P = 0.012). The findings suggest that segmental LFI osteotomy is safe when performed with a bur and osteotome, provided a minimum distance of 2.5 mm between roots is maintained.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142585428","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 intergonial width increased after surgery, by 2.78 ± 2.02 mm in group I, 2.86 ± 2.81 mm in group II, and 2.53 ± 2.42 mm in group III (all P < 0.001). The mandibular angle (MA) increased in group I (ΔMA 4.76 ± 2.79°; P < 0.001) and group III (ΔMA 3.50 ± 2.58°; P < 0.001); however no significant increase was observed in group II. The increase in intergonial width was positively correlated with the lateral displacement of the proximal segment. Counterclockwise rotation of the proximal segment resulted in an increase in MA, while counterclockwise rotation resulted in a reduction in this increasing trend.

Existing classifications for the resulting midfacial defects are inconsistent and have issues regarding terminology, therefore a consensus is needed. The aim of this review was to analyse the previously published classifications, identify defining parameters, determine their strengths and weaknesses, and propose a universal classification for midfacial defects with the goal of being sufficiently detailed yet easily applied in clinical practice. A scoping review was conducted according to the PRISMA guidelines using the PubMed, Embase, and Wiley Online Library electronic resources. Analysis of the various midfacial resection classifications identified in the search revealed common parameters including anatomical landmarks, the walls removed, and the presence of oroantral communication, as well as an accompanying algorithm and options for reconstruction. The articles with the most detailed descriptions were noted. A new classification is proposed that includes elements of the three most detailed existing classifications, incorporating the vertical and horizontal extents of the defect, but with more specific details concerning severity and aimed at greater practical clinical utility.","PeriodicalId":94053,"journal":{"name":"International journal of oral and maxillofacial surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142515314","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}

This model was validated by studying different cephalometric points in three modules (vertical dimensions, sagittal dimensions, and symmetry) and their sections. Each section of the different modules evaluates the range of the studied patient according to the TFA analysis executed in Planmeca Romexis software and compares it with the ProPlan CMF data. The results of the statistical analysis defined the degree of concordance for each point studied. An overall high correlation was demonstrated for each of the cephalometric categories (weighted kappa between 0.442 and 0.642 in vertical dimension, between 0.587 and 1 in sagittal dimension, and between 0.773 and 1 in symmetry).

Four studies described SI assessment methods, which were DS-MV, PHQ-9, Beck Scale for Suicidal Ideation, and psychiatric interviews. Older age, depression, demoralization, previous cancer history, psychiatric history, alcohol dependence, anxiety, living alone, and poor quality of life were frequently mentioned as risk factors of SI. The prevalence of SI varied across studies and was probably affected by the method of assessment, treatment, and postoperative care. SI was consistently predicted with psychological distress.

Thirty-one patients who underwent LFI using SuperFIXSORB-MX were evaluated retrospectively. The patients were divided into four malocclusion types: open bite, mandibular retrognathia, mandibular protrusion, and facial asymmetry. Seven maxillary reference points were measured three-dimensionally using computed tomography scans obtained preoperatively (T0), 4 days post-surgery (T1), and 1 year post-surgery (T2). Surgical changes (T1-T0) and the postoperative discrepancy (T2-T1) of the maxilla were analysed to evaluate postoperative stability by surface superimposition of the virtual LFI segments. Postoperative discrepancy was the largest for the facial asymmetry type, ranging from 0.75 ± 0.45 mm to 0.98 ± 0.52 mm in three-dimensional distance (minimum to maximum mean ± standard deviation values for the individual reference points). The relapse at U1 was 16% in the transverse axis, and the anterior nasal spine moved further upward by 17% of the amount of movement of the maxilla.
