Aim:The aim of this study was to detect and describe the patterns of implant prosthetic treatment modalities placed in partially and fully edentulous Saudi patients restored with dental implants in Saudi Arabia, and to detect the status of the health insurance covering dental implants in Saudi Arabia. Materials and Methods: 520 Saudi patients aged ≥18 years residing in Saudi Arabia and treated with at least one dental implant done in dental health premises in Saudi Arabia were randomly included in the study. Clinical and radiographic examination were used to detect implant prostheses types (single-tooth implant, implant-supported long or short span conventional fixed bridge, implant overdenture). The health insurance covering dental implants was detected too. The data obtained including age, gender, systemic disease, and tobacco smoking were documented in a patient examination form then statistically analyzed using Chi-Square Test and U-Test. Results: The most frequently tooth type replaced by dental implants was the molars (45.5%), followed by premolars (40%), incisors (7.7%), and canines (6.8%); mandibular first molars were the most common tooth type replaced by implants. Single-tooth implant was the most common prosthetic treatment modality (85.2%), followed by implant-supported short span conventional fixed bridge (9.8%), implant overdenture (2.8%), and implant-supported long span conventional fixed bridge (2.2%). The majority of implant overdenture prostheses were seen in the age group ≥ 60 years. Implant-supported long span fixed bridge prostheses were more in patients aged ≥ 50 years than in patients aged < 50 years, while single-tooth implant prostheses were more in patients aged < 50 years than in patients aged ≥ 50 years. Of all teeth types replaced by dental implants, molars were the most common type seen in implant-supported long span fixed bridges and in single-tooth implants, whereas canines were the most common type seen in overdentures. There was an insignificant difference in the median number of dental implants between males and females. Conclusion: Single-tooth implant is major. Health insurance policy doesn’t cover dental implants in Saudi Arabia. Keywords: Implant, Modalities, Prostheses/Prosthetic, Type

Aim: The aim of this study was to detect and analyze dental malpractice in the field of implant dentistry in the Kingdom of Saudi Arabia. Materials and Methods: 106 patients aged ≥ 18 years with at least one professional malpractice in implant dentistry done in dental health premises in Saudi Arabia were included in the study. Clinical and radiographic examinations were used to detect preoperative (diagnosis and treatment planning), intraoperative (implant insertion), and postoperative (post surgery and prosthesis) complications. The data obtained including age and gender were documented in a patient examination form then statistically analyzed using Chi-Square Test and Spearman’s Correlation Coefficient. Results: The percentages of patients were equally divided among the preoperative, intraoperative, and postoperative phases p > 0.05. More than half of the patients were females (61.3%). The majority of the patients were in the age group 50-60 years. Also, the majority of the patients had implants with malpractice placed in the posterior region. Exactly half of the patients had implants with malpractice placed in the maxilla. In addition, exactly half of the patients had technical errors violating the surrounding structures; (37.7%) of the patients had damage to adjacent tooth and (11.3%) had inferior alveolar nerve damage; also, (4.7%) of them had sinus penetration. Furthermore, at the patient level, age and gender were not related to implant failure, and (75.5%) of the patients had implant failure. With respect to peri-implantitis, patients ≥ 50 years of age were more than patients < 50 years of age. However, gender and maxilla were not related to peri-implantitis. The prevalence of peri-implantitis was 20.8% at the patient level. In partially edentulous patients, implant fracture was (1.17%) at the implant level. Conclusion: Implant malpractice equally occurred among the preoperative, intraoperative, and postoperative phases.
