One of the most challenging and demanding endeavors in the field of prosthodontics is the rehabilitation of an edentulous mandible. Implants have been used to support mandibular or maxillary prosthetic rehabilitation. Advantages of using implants are increased retention, increased chewing ability, and also easy access to oral hygiene procedures. For decades, the use of telescopic and conical crowns are in practice to connect natural teeth and not many cases have been reported in the literature of telescopic crowns placed on implants to support the prosthesis. Telescopic crowns provide the best possible distribution of force to the abutment teeth and can improve the patient's oral health-related quality of life. The use of telescopic crowns as attachments for implant-supported overlying prostheses may be a viable treatment option for edentulous mandible. The functional and the aesthetic enhancement by telescopic retainers are favorable features for many challenging situations. This case report discusses a 60-year-old male, who reported to the department of prosthodontics with three implants and two bi-cortical screws that were placed in a completely edentulous mandibular arch by a private practitioner one year back and this situation was prosthodontically managed by us with an implant-supported telescopic removable prosthesis.
口腔修复学领域中最具挑战性和要求严苛的工作之一是无牙下颌骨的修复。种植体已被用于支持下颌或上颌的修复。使用种植体的优点包括固位力增强、咀嚼能力提高，以及便于进行口腔卫生护理。几十年来，套筒冠和圆锥冠一直用于连接天然牙，而文献中报道的将套筒冠用于种植体以支持修复体的情况并不多。套筒冠能将力最佳地分布到基牙上，并可改善患者与口腔健康相关的生活质量。将套筒冠用作种植体支持的覆盖义齿的附着体，对于无牙下颌骨可能是一种可行的治疗选择。套筒冠固位体在功能和美观方面的提升，对于许多具有挑战性的情况来说都是有利的特点。本病例报告讨论了一名60岁男性，他一年前由一名私人执业医生在下颌完全无牙的牙弓中植入了3颗种植体和2颗双皮质螺钉，随后前来口腔修复科就诊，我们采用种植体支持的套筒冠可摘义齿对这种情况进行了修复治疗。
