A total of 11 implants placed in 8 patients were studied. The patients were men or women between 30 and 50 years of age who were undergoing orthodontic treatment and whose treatment planning required skeletal anchorage. All implants were placed in the posterior mandibular region. When osseointegration of the implants was complete (4 months after placement), radiography and initial resonance frequency analysis were performed at the orthodontic loading appointment (T1). New examinations were performed 6 months after orthodontic loading (T2). The examinations showed a gain in bone height and an increase in implant stability quotient at T2. The greater gain observed at the mesial surface of the implant, which was the site of greater compression for most implants, was due to the applied mechanics. These results suggest that the use of osseointegrated implants for orthodontic anchorage does not interfere with their osseointegration, and the use of light, constant orthodontic forces can stimulate bone formation in stress areas and improve implant stability.</p>","PeriodicalId":12571,"journal":{"name":"General dentistry","volume":"74 2","pages":"32-36"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147316710","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 literature review will explore the potential of AI systems to revolutionize the field of dentistry as well as their current limitations. Applications in development optimize the efficiency and accuracy of diagnosis and treatment planning in all areas of dentistry, showing success in detecting conditions such as dental caries, periodontal disease, and periapical lesions. In addition, AI has proven useful in analyzing features on dental images for purposes such as orthodontic treatment planning, implant placement, and third molar extraction. While these applications hold significant promise in shaping the future of dentistry, several limitations and challenges must be addressed before AI is adopted for widespread use. Among the concerns are ethical considerations regarding data security and patient consent as well as the potential for biases and error arising from limited training datasets. Once these issues are resolved, AI will represent a powerful tool for transforming the future of dentistry.</p>","PeriodicalId":12571,"journal":{"name":"General dentistry","volume":"74 2","pages":"62-68"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147316726","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}

A 71-year-old man sought prosthetic restoration of an extensive surgical defect that involved the right orbital floor, maxilla, and palate. The treatment plan involved fabrication of maxillofacial and palatal obturator prostheses that would be connected by magnets as well as a conventional total mandibular prosthesis. Intraoral and extraoral impressions were made with irreversible hydrocolloid, and stone casts were prepared. Test bases and wax rollers were made on the arch casts, which were adjusted and mounted on an articulator. Artificial teeth were selected and mounted on the test bases. After clinical and functional testing of the waxed-up prostheses and selection of the resin colors, the prostheses were processed in heat-activated acrylic resin. Waxing was performed on the maxillofacial cast, and the wax pattern was tested on the patient's face. To determine the location of the magnets, zinc oxide paste was applied to the inner surface of the wax pattern, and both the obturator prosthesis and wax pattern were positioned on the patient. A hole was opened in the bulb of the obturator at the location demarcated by the paste when the surfaces of the extraoral and intraoral prostheses made contact. A magnet was bonded inside the hole with chemically activated acrylic resin. An acrylic capsule was fabricated to house another magnet and positioned at the corresponding location on the inner surface of the wax pattern. The wax pattern was placed in a muffle furnace to generate a mold for compression of intrinsically pigmented silicone, which had been selected to match the patient's skin color. After polymerization, the prosthesis underwent finishing and extrinsic pigmentation to better the capture the nuances of the patient's skin tone. A pair of eyeglasses was bonded to the maxillofacial prosthesis to increase stability. The combined prostheses restored esthetics and function to the patient, fostering his social reintegration.</p>","PeriodicalId":12571,"journal":{"name":"General dentistry","volume":"74 2","pages":"39-44"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147316912","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}

Clinically, CGCG can present in various forms, from small lesions to large, painful lesions. Radiographically, it appears as a radiolucent area; on histopathologic analysis, lesions show multiple giant cells. This case report describes an extensive CGCG in the maxilla of an 11-year-old girl who initially experienced painless swelling on the anterior hard palate. Clinical and radiographic examinations initially raised concerns of a possible malignancy, but incisional biopsy and histopathologic analysis established the diagnosis of CGCG. Following surgical removal of the lesion and prosthetic replacement of teeth extracted during lesion excision, the patient has remained healthy and recurrence-free for 31 years. Maxillary CGCG is an uncommon lesion, and its treatment depends on the particular clinical features. Regular, long-term monitoring is essential for detecting possible recurrence and to promote better understanding of the clinical behavior of this lesion.</p>","PeriodicalId":12571,"journal":{"name":"General dentistry","volume":"74 2","pages":"69-73"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147316875","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}
