The present report describes the case of a patient who underwent maxillary sinusitis right after dental implant installation with sinus lifting. Computed tomography scan revealed a dental implant (#16) was protruded inside the right maxillary sinus and confirmed the obstruction of ostium. A symptom remission was gained with the dual approaches combined by functional endoscopic sinus surgery and an intra-oral approach. Fully recovered function and healing of sinus were identified after 10 months follow-up. We report the case of sinusitis caused by protrusion of implants with sinus floor lift procedures and propose that practitioners should be aware of the possible its complications and management.

Early childhood caries is a global healthcare concern in developing and industrialized countries. If left untreated, it leads to immediate and long-term complications that affect the well-being and quality of life of concerned families. Therefore, many preventive and treatment approaches are available to the healthcare provider to curb this virulent form of caries. After behavioral interventions, general anesthesia is used in specific settings when a young patient presents with extensive teeth damage and exhibits a lack of cooperation that is incompatible with conventional dental office care. However, without proper follow-up, any positive results might be lost over time.

Construction of an obturator for rehabilitation of a patient who underwent a maxillectomy is vital. Routinely a constructed obturator includes denture portion. A patient who may present anatomical limitations due to surgical or radiotherapy complications often challenges the clinician. Purpose: This clinical report describes a patient with severe trismus after surgical resection and radiotherapy treatment of a tumor in the upper left maxilla. Conclusion: This report describes the concepts of using a rotational path insertion for an obturator and a separately constructed maxillary denture. The stability and retention of the obturator were obtained from anatomical features. Where as these were achieved through magnetic attachments and the remaining edentulous ridge to ensure esthetic and function of the prosthesis.

General anesthesia has been developed in dentistry as a type of management technique to sedate patients who may be uncontrollable or require medical consideration. However, emergency treatment for controlling pain before general anesthesia could be required due to the time for medical evaluation for general anesthesia. There is a greater possibility of developing complications under extended waiting period. A disabled patient who needs dental treatment under general anesthesia underwent pretreatment with intramuscular injection of midazolam and $N_2O-O_2$ inhalation sedation in these cases report.

Benign fibro-osseous lesions occur when normal bone is replaced by cellular fibrous connective tissue and mineralized structures. One rare type of these lesions is the ossifying fibroma (OF). The aim of this study is to report an unusual case of OF in a 57-year-old female. Physical examination showed facial asymmetry without any tenderness, fluctuation, ocular pain, or ophthalmoplegia. Imaging exams revealed a solid mass involving the left maxilla and orbital floor. Surgical resection was performed without any complications or sequelae, and the histopathological results confirmed OF. Although recurrence is rare in this condition, the patient remains under follow-up.

The geriatric population is the most rapidly growing part of the general population, which leads to an increase of chronic conditions and illnesses that will influence both oral and systemic health. The most common chronic diseases in elderly population are arthritis, hypertension, heart diseases, diabetes, and cognitive impairment. Chronic impairments such as visual, hearing, orthopedic, and speech disorders are also prevalent among older adults. All these chronic conditions have potential oral complications and the treatments of systemic diseases also has implications for the maintenance of oral health. Therefore, oral health care professionals should catch up with increasing knowledge in this field and can modify the treatment strategy for older adults. In addition, oral health care professionals should understand the changing need of oral health problems in this age and prepare the future demand.

This study aims to describe the clinical experience of single and bridge crowns fabricated using a cementless screw-retained implant prosthesis system. In the case of single crown (#37), regular link (HDL) was used, and bridge crowns (#15~#24), (#26~#27), (#17~#14) (#24~#26) were fabricated by selecting regular link and short link considering the vertical height. One abutment was hex shaped to ensure that it could be mounted while preventing insertion and prosthesis rotation. The advantages of cementless implant prosthesis include shorter chair time and periodic care, strong retention with LINK abutment, safety from inflammation, bacterial infection, and complications due to peri-implant cement, and high patient satisfaction. Dentists should double-check the position of the implant fixture and dental technicians should continuously manage the fit of the link and prosthesis with digital equipment to reduce screw loosening and fractures.

Prosthetic restorations through implants were popularized, and they became routine treatments. Small accessories used in the implant prosthodontic procedure are more likely to slip or fall off the dentist's hands. If the dental appliance or material passes into the upper gastrointestinal tract, there is a high possibility of excretion to the outside of the body without complications, but serious complications may occur depending on the type of foreign body. If the foreign body is passed to the airway, it is an emergency situation, and if it is not done properly, it can be fatal. The purpose of this review report is to investigate the process of foreign body ingestion or aspiration during dental treatment, and the method of prevention and treatment.

Dental extraction is potentially stress-inducing in many disabled patient. The body's response to dental stress involves the cardiovascular system(an increase in cardiovascular workload), the respiratory organ and the endocrine system(change in metabolism). To minimize the stress, the stress reduction method was established. The obtained contents were as follows: (1) Recognize the patient's degree of medical risk, (2) Complete medical consultation before dental therapy, (3) Schedule the patient's appointment in the morning, (4) Monitor and record preoperative and postoperative vital signs, (5) Use psychosedation during therapy, (6) Use adequate pain control during therapy, (7) Short length of appointment : do not exceed the patient's limits of tolerance, (8) Follow up with postoperative pain/anxiety control, (9) Telephone the risk patient later on the same day that treatment was given. Though the stress reduction method above was applied to the dental extraction in disabled patients with the advanced infected teeth, the complications(syncope, shock, bleeding & infection, etc.) may be occurred. For prevention of complications associated with the extraction, the authors treated the advanced infected teeth with endodontic drainage and incision & drainage before extraction. The final extraction and wound closure were then done after about 3 weeks.

PURPOSE. To compare the clinical outcomes of two types of implant restoration for posterior edentulous area, 3-unit bridge supported by 2 implants and 3 implant-supported splinted crowns. MATERIALS AND METHODS. The data included 127 implant-supported fixed restorations in 85 patients: 37 restorations of 3-unit bridge supported by 2 implants (2-IB), 37 restorations of 3 implant-supported splinted crowns (3-IC), and 53 single restorations (S) as controls. Peri-implantitis and mechanical complications that occurred for 14 years were analyzed by multivariable Cox regression model. Kaplan-Meier curves and the multivariable Cox regression model were used to analyze the success and survival of implants. RESULTS. Peri-implantitis occurred in 28.4% of 2-IB group, 37.8% of 3-IC group, and 28.3% of S control group with no significant difference. According to the implant position, middle implants (P2) of the 3-IC group had the highest risk of peri-implantitis. The 3-IC group showed a lower mechanical complication rate (7.2%) than the 2-IB (16.2%) and S control group (20.8%). The cumulative success rate was 52.8% in S (control) group, 62.2% in 2-IB group, and 60.4% in 3-IC group. The cumulative survival rate was 98.1% in S (control) group, 98.6% in 2-IB group, and 95.5% in 3-IC group. There was no significant difference in the success and survival rate according to the restoration type. CONCLUSION. The restoration type was not associated with the success and survival of implants. The risk of mechanical complications was reduced in 3 implant-supported splinted crowns. However, the middle implants of the 3 implant-supported splinted crowns had a higher risk of peri-implantitis.
