Study design:

Cohort study 

研究目的:

通过回顾性研究分析后牙种植全锆单冠修复延迟咬合设计下与不同设计对颌牙在局部咬合变化过程中的磨损方式及局部牙列咬合特征变化规律,明确其与修复后并发症、植体周健康水平等指标的相关性,为种植全锆冠的咬合设计、调整和长期维护提供理论依据。  

Objectives of Study:

The aim of this study is to analyze the wear pattern of posterior implant-supported full zirconia crowns under light bite delayed occlusal design with differently designed opposing teeth, and the changing law of local occlusal characteristics through a retrospective study. The study will clarify their correlation with complications, peri-implant health level and other indicators. It will also provide a theoretical basis for the occlusal design, adjustment and long-term maintenance of implant-supported full zirconia crowns.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

a) 单侧后牙区已完成种植体支持式全锆单冠修复至少5年(邻牙为天然牙,牙冠形态基本完好,牙冠轴向及位置无明显异常); b) 修复体对颌牙为无大面积充填体的天然牙,或已完成种植体支持式/天然牙支持式全锆单冠修复; c) 邻牙、对侧同名牙的对颌牙均为未行冠修复的天然牙(无大面积充填体),无明显根尖周阴影,修复体对颌牙为天然牙者亦无明显根尖周阴影; d) 患者年龄在18-75岁之间,男女不限; e) 咬合检查无明显异常(无早接触或咬合干扰),双侧后牙有稳定的咬合接触; f) 保存有完整、可靠的种植术前、术中、术后资料; g) 患者同意参加本试验,并签署知情同意书。

Inclusion criteria

a) The unilateral posterior region has had an implant-supported full zirconia single crown restoration for at least 5 years (the adjacent tooth is a natural tooth whose crown is almost intact and there is no obvious abnormality in the axial direction and position of the crown). b) The zirconia single crown opposes either to a natural teeth without large fillings, or implant-supported/natural-tooth supported full zirconia single-crown restorations. c) The adjacent teeth and the corresponding tooth on the contralateral side oppose to natural teeth without crown restorations or large fillings, without obvious periapical shadows. There is no visible periapical shadowing of the tooth when the implant-supported full zirconia single crown opposes to a natural tooth. d) The patient is between 18 and 75 years old without gender restrictions. e) There are no obvious abnormalities on occlusal examination (no premature contact or occlusal interference) and the bilateral posterior teeth have stable occlusal contacts. f) Complete and reliable preoperative, intraoperative and postoperative implant data have been recorded and preserved well. g) The patient agreed to participate in this study and signed an informed consent form.

排除标准:

a) 无法配合定期随访或影像学检查的患者; b) 存在张口受限或影响下颌运动的口颌系统肌肉、骨骼、关节疾病; c) 有中重度牙周病史或种植体周围病史; d) 存在严重的牙列不齐或修复后有正畸治疗史; e) 服用类固醇或双膦酸盐类药物; f) 患者有影响护理口腔卫生的身体残疾或精神疾病; g) 种植术区曾进行过骨增量手术; h) 修复后进行了患侧后牙区拔牙,或邻牙/对颌牙/对侧同名牙进行了咬合面累及牙尖的充填或修复治疗; i) 患者有偏侧咀嚼的不良习惯。

Exclusion criteria:

a) Patients who are unable to cooperate with regular follow-up or imaging examination. b) Presence of restricted mouth opening or muscular, skeletal, joint disorders of the stomatognathic system affecting jaw movement. c) A history of moderate to severe periodontitis or peri-implant disease. d) Presence of severe malocclusion or history of orthodontic treatment after restoration. e) Use of steroids or bisphosphonates. f) Patients who have a physical disability or mental illness interfering with oral hygiene maintenance. g) A history of bone augmentation surgery in the area of the implants. h) Tooth extraction in the posterior region of the affected side or resin filling or restoration of occlusal surface involving the cusp has been performed on the adjacent teeth, the opposing tooth or the corresponding tooth on the contralateral side after implant-supported full zirconia single crown restoration. i) Patients with unilateral chewing habits.
