- Purpose: Dental implant displacement into the maxillary sinus can be performed intraoperatively, during the healing phase and after loading. We aimed to describe the etiology, sequela, and treatment in each stage by presenting 27 sinus migration cases. Materials and Methods: Twenty-seven patients presenting with displaced implants into the maxillary sinus were included in this study. All the patients were referred from the local dental clinic. They comprised 18 men and 9 women, with a mean age of 58 years. We examined the location of the displaced implant, time of displacement, etiology, presence of sinusitis, and implant operation technique. The dental implants were removed by a lateral approach with endoscope-assisted surgery upon no visualization by lateral window formation. Results: The implants were displaced into the maxillary sinus during operation (5 cases), during healing periods (15 cases), and after loading (7 cases). Ratio of the right to left side was 13:14. The lateral approach (6 cases) and osteotome technique (21 cases) were used for implant placement. Membrane perforation during operation was the most common etiology for sinus migration. Implant displacement occurred in two cases during the removal of fractured implant. The displaced implants were removed by a lateral approach to the maxillary sinus. Conclusion: Implant displacement was predominant during the healing period and for the osteotome technique. Unnoticed membrane perforation during implant placement in the posterior maxilla may cause dental implant displacement into the maxillary sinus. Osteotome sinus floor elevation should be utilized carefully to prevent implant migration. The lateral approach with endoscope visualization facilitated displaced implant removal. - COLLAPSE

- Prosthetic Rehabilitation in Patients with Severe Hearing Disability and Loss of Occlusal Vertical Dimension: A Case Report

- A thorough examination and diagnosis are required for full-mouth rehabilitation with increased vertical dimension. However, due to a lack of communication or cooperation, the essential process for full rehabilitation with increased vertical dimension (including face-bow and check bite in centric relation as well as anterior guidance) is problematic for the majority of impaired patients. Nonetheless, because of the high prevalence of caries or periodontal disease, disabled people require full-mouth rehabilitation more frequently than non-disabled patients. The purpose of this case study is to describe a case of full-mouth rehabilitation with increased vertical dimension in a patient with hearing impairment. - COLLAPSE

- The laboratory procedure of complete mouth rehabilitation is challenging when it comes to proceeding by reflecting the previous step to the next. This case report describes integration of multi-source digital data and the design of prosthesis using a computer-aided design program to address these issues. The facial scan, jaw motion analyzer, and intraoral scan were combined and reflected in the design of the prosthesis. The predictability of the treatment was improved by creating a virtual patient, utilizing a virtual articulator, and employing a double scanning technique. - COLLAPSE

- Among various benign fibro-osseous (BFO) lesions, cemento-osseous dysplasia (COD) is the most prevalent pathology. Placement of implants in the BFO tissue, especially in a jaw with COD, often presents clinical concerns. In this case report, we present an instance of complete removal of COD followed by bone grafting, and subsequent implant placement after confirming the restoration of normal bone structure. Radiographs confirmed that the implant and normal bone could be maintained without any problems during the long-term follow-up period. The area where COD was removed was filled with collagen material or xenogenic bone and replaced with normal bone. Therefore, if the COD lesion is removed from the area, replaced with normal bone, and an implant is placed, reasonable and stable outcomes can be anticipated. - COLLAPSE

- Microstomia is caused by congenital growth abnormalities, exposure to electricity or chemicals, or direct burns. In the case of burn-induced microstomia, treatment is difficult because of fibrosis at the burn site. During dental treatment, buccal retraction is necessary to access the posterior teeth. When performing maxillary sinus augmentation using the lateral approach, sufficient buccal retraction through the buccal vestibule is required. Implant placement with sinus augmentation in patients with burn-induced microstomia caused by is very difficult to treat. Herein, we describe the successful results of simultaneous bilateral sinus augmentation and implant placement along with commissuroplasty and upper-lip reconstruction using mucosal advancement in a patient with burn-induced microstomia. - COLLAPSE
