研究目的:

主要研究目的是比较传统咬合记录方法与新型咬合记录杆在游离末端缺失种植修复体咬合精度、临床咬合调整时间、修复体咬合舒适度等方面的差异,评估新型咬合记录杆的临床应用价值。  

Objectives of Study:

The primary objective of this study is to compare traditional occlusal recording methods with a novel occlusal recording rod in terms of occlusal accuracy, clinical occlusal adjustment duration, and prosthetic occlusal comfort for implant-supported prostheses in cases of free-end edentulism, thereby evaluating the clinical application value of the novel occlusal recording rod.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

(1)年龄大于18岁; (2)无未经控制或治疗的牙周疾病; (3)游离末端连续缺失2个或以上相邻后牙(第三磨牙不计),且已完成种植体植入及骨整合,分为三类:单侧单颌类、单侧双颌类、双侧单颌类; (4)剩余牙列具有可重复且稳定的口内最大牙尖交错位 (MIP)。

Inclusion criteria

(1)Age greater than 18 years. (2)Absence of uncontrolled or untreated periodontal disease. (3)Terminal free-end continuous edentulism involving two or more adjacent posterior teeth (excluding third molars), with completed implant placement and osseointegration. Subcategorized into three types: Unilateral single jaw, Unilateral double jaw, Bilateral single jaw. (4)Presence of a repeatable and stable intraoral maximum intercuspation position (MIP) in the remaining dentition.

排除标准:

(1)剩余牙?丧失牙尖交错位或全口无牙; (2)颞下颌关节疼痛不适; (3)经询问和检查确诊的牙周不良习惯(例如咬牙、磨牙)。

Exclusion criteria:

(1)Loss of maximum intercuspation in the remaining dentition or complete edentulism. (2)Presence of temporomandibular joint (TMJ) pain or discomfort. (3)Parafunctional oral habits (e.g., clenching, bruxism) confirmed through history-taking and clinical examination.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用计算机生成的随机数字表法进行随机分组。由不参与患者招募与评估的研究统计人员使用统计软件(如SPSS或R语言)生成随机序列,将四类患者(单侧单颌类、单侧双颌类、双侧单颌类、双侧双颌类)分别随机分配至实验组(新型种植体支持咬合定位器)或对照组(传统咬合记录方法)。分组结果采用密封信封法进行隐藏,确保分配过程不可预测。

Randomization Procedure (please state who generates the random number sequence and by what method):

This study employs a computer-generated random number table for randomization. A study statistician, who is not involved in patient recruitment or evaluation, will use statistical software (e.g., SPSS or R) to generate random allocation sequences. Four categories of patients (unilateral single jaw, unilateral dual jaw, bilateral single jaw, bilateral dual jaw) will be separately randomized into either the experimental group (novel implant-supported occlusal index) or the control group (traditional occlusal registration method). Allocation concealment will be implemented using sequentially numbered, sealed, opaque envelopes to ensure the unpredictability of the assignment process.
