Abstract

Background: The success rate of dental implants depends on the amount of crestal bone around the implants. Crestal module is the transosteal region of implant that is designed to receive the prosthetic component. The design of crestal module influences the crestal bone loss around implants.

Aim: The purpose of this study was to evaluate and compare the crestal bone loss around implants with smooth collar and implants with micro threaded rough collar design.

Materials and methods: A total of 150 individuals received 100 dental implants. Each individual received one implant with smooth collar design (Group-A) and one implant with microthreaded rough collar design (Group-B) in the posterior edentulous region. All the 100 implants were prosthetically loaded after a healing period of 3 months. Crestal bone loss was measured on mesial, distal, buccal, and lingual side of each implant using periapical radiographs before loading (baseline), immediately after loading, 6, and 12 months after loading.

Results: The average crestal bone loss 12 months after loading the implants in Group A and Group B was 3.75 mm and 3.23 mm, respectively, the value being statistically significant (P < 0.05). In both Group A and Group B, the average crestal bone loss was maximum on the lingual side followed by buccal, distal, and mesial sides.

Conclusion: Crestal bone loss around rough-surfaced microthreaded neck implants was significantly lower than smooth-surfaced neck implants.

种植体颈部设计对牙冠骨丢失影响的比较研究。

背景:种植体的成功率取决于种植体周围牙冠骨的数量。嵴模块是植入体的跨骨区域，用于接收假体组件。牙冠模的设计影响种植体周围牙冠骨的流失。目的:评价和比较光滑领种植体与微螺纹粗领种植体的牙冠骨丢失情况。材料与方法:150例患者共种植100颗牙。每个患者在后牙无牙区接受1个平滑环设计种植体(a组)和1个微螺纹粗糙环设计种植体(b组)。所有100个种植体在愈合3个月后进行假体加载。在装填前(基线)、装填后立即、装填后6个月和装填后12个月，通过根尖周x线片测量每个种植体的中、远端、颊侧和舌侧的嵴骨损失。结果:A组和B组在种植体加载后12个月平均牙冠骨丢失量分别为3.75 mm和3.23 mm，差异有统计学意义(P < 0.05)。在A组和B组中，舌侧平均嵴骨丢失最大，其次是颊侧、远端和中侧。结论:表面粗糙的微螺纹颈种植体的牙冠骨丢失明显低于表面光滑的颈种植体。
