Increased thickness of an unhealthy membrane generally indicates a weaker membrane with a gelatinous texture, whereas thickening of a healthy membrane occurs at the periosteal layer level and can enhance its strength. Sinus membrane thickness, sinus septa, type of edentulism, and root position relative to the sinus cavity, residual bone height, sinus width, palatonasal recess angle, buccal wall thickness, zygomatic arch location, alveolar antral artery, and bone dehiscence may influence the clinical complexity of the surgery. There is no clear evidence of systematic negative outcomes related to sinus perforations. In patients with severely atrophic posterior maxillas, the possibility of lacerating the alveolar antral artery and/or detecting antral septa must be considered, especially when the residual ridge height is < 3 mm high. Transient edema and thickening of the sinus mucosal membrane typically resolve spontaneously. In cases of graft extrusion, conservative management could be considered for asymptomatic patients with healthy sinus and open ostium at the time of surgery. On the other hand, patients with symptoms should be referred. Radiographic evidence of implant protrusion into the sinuses is not always associated with complications.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Investigating sinus homeostasis and physiology, exploring the vascular anatomy within the maxillary sinus, identifying anatomical risk factors for sinus membrane perforation, and analyzing the significance of preoperative and postoperative sinus CT imaging provide a systematic and comprehensive framework for evaluating the complexity of maxillary sinus augmentation using a lateral approach.</p>\u0000","PeriodicalId":50679,"journal":{"name":"Clinical Implant Dentistry and Related Research","volume":"27 2","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patient had received two titanium alloy implants in the same area 7 and 3 years ago, respectively, for missing posterior teeth. Clinical examination revealed soft tissue hyperplasia and easy bleeding upon touch around the implants supporting the prosthetic restoration at Sites 24 and 25. Radiographic evaluation showed no significant bone resorption. Initial management included the prosthetic restoration removal, placement of healing abutments, and peri-implant curettage with the application of medication. After 10 days, the lesion was surgically excised, and histopathological analysis confirmed the diagnosis of PG. Despite initial treatment, the lesion recurred 2 weeks after excision. A second excision, coupled with debridement and local medication, was performed. However, the PG recurred 3 weeks later, necessitating the implants removal at sites 24 and 25. Following implants removal, the surgical sites were monitored for 3 months, during which no PG recurrence was observed. Given the patient's systemic health and the local soft and hard tissue conditions, the tooth at site 26, which had a poor prognosis, was also extracted. Subsequently, reimplantation was performed at sites 24, 25, and 26. After a six-month healing period, the prosthetic restoration was completed. Three and six months post-restoration, clinical and radiographic evaluations confirmed stable outcomes, with no abnormalities in the peri-implant soft or hard tissues.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Peri-implant PG is a relatively rare soft tissue complication associated with dental implants and is characterized by a high recurrence rate, often leading to implant removal. This case illustrates successful reimplantation at the original site following implant removal due to PG, providing clinical evidence that reimplantation after PG-related implant failure is feasible. However, a thorough evaluation of both systemic and local factors is essential to minimize recurrence and ensure successful outcomes.</p>\u0000 </section>\u0000 </div>","PeriodicalId":50679,"journal":{"name":"Clinical Implant Dentistry and Related Research","volume":"27 2","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
