When the inferior alveolar canal is extremely close to the alveolar crest, conventional dentures risk causing severe pain and sensory abnormalities by compressing the inferior alveolar nerve. Thus, conventional fabrication methods face clinical limitations. To stabilize a mandibular complete denture in such cases, it is highly effective to record the dynamics of the denture space and fabricate a prosthesis that harmonizes with these perioral muscle movements. A 77-year-old woman presented with frequent stomatitis caused by ill-fitting dentures and severe masticatory dysfunction. Intraoral and radiographic examinations revealed marked resorption of the mandibular alveolar ridge, placing the inferior alveolar canal in extreme proximity to the alveolar crest. The treatment plan involved fabricating a new maxillary partial denture that strictly balanced the support of the remaining teeth. For the mandible, a complete denture was fabricated using the neutral zone and flange techniques to harmonize with surrounding soft tissue movements. This approach enabled functional contouring by leveraging the dynamic pressure of the perioral muscles. Consequently, denture retention and stability improved dramatically, and denture displacement during speech was successfully suppressed. An evaluation of masticatory function confirmed objective functional recovery. This case demonstrates that for patients with severe alveolar ridge resorption and diminished anatomical supporting tissues, determining the functional form of the denture by accounting for soft-tissue dynamics is highly effective in restoring stability and masticatory function.</p>","PeriodicalId":46841,"journal":{"name":"Case Reports in Dentistry","volume":"2026 ","pages":"6174765"},"PeriodicalIF":0.9,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13659418/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149184975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although typically asymptomatic, they can occasionally lead to severe infectious complications. This report describes a rare case of an infected complex odontoma manifesting as a cutaneous fistula, emphasizing the surgical challenges associated with its anatomical location. A 22-year-old male presented with a 1-month history of a cutaneous fistula at the left mandibular angle and intraoral bone exposure. Radiographic evaluation (panoramic and CBCT) revealed a voluminous radiopaque mass at the mandibular angle, which had severely displaced the third molar toward the inferior border of the mandible. The proximity to the inferior alveolar nerve and the thinness of the remaining bone posed a significant risk of iatrogenic fracture. The patient underwent surgical enucleation of the lesion and extraction of the displaced molar. To mitigate the risk of mandibular fracture and nerve injury, piezoelectric surgery was utilized. The use of ultrasonic inserts allowed for a precise, selective osteotomy and a safe extraction, preserving the structural integrity of the weakened mandible. Histopathological analysis confirmed the diagnosis of a complex odontoma associated with dentigerous cyst. At the 6-month follow-up, the cutaneous fistula had completely resolved with excellent healing and no sign of recurrence.
