Abstract

Purpose: The aim of this study was to evaluate the marginal bone loss (MBL) over a follow-up period of up to 36 months in Immediate dental implants (IDIs), as well as the impact of various clinical variables on the MBL.

Methods: IDIs placed in two surgical phases were evaluated. Implants were classified into bone loss (BL, exposed threads), bone remodeling (BR, crestal bone at the implant margin ± 0.1 mm), and bone overlapping (BO, bone above the abutment).

Results: A total of 1,040 IDIs were inserted in 344 patients with a successful osseointegration rate of 98.9%. The average MBL at 2, 6, 12, 24, and 36 months was - 0.3 ± - 1.0 mm, - 1.1 ± -1.8 mm, - 1.4 ± - 1.8 mm, - 1.7 ± - 1.9 mm, and - 1.3 ± - 2.3 mm, respectively. In the Baseline-12-month period, 17.5% of the IDIs presented BL, 9% BR, and 73.5% BO. For the B1-12 month period, 19.8% presented BL, 10.7% BR, and 69.5% BO. Mixed regression models showed significant MBL overtime pre-loading (p < 0.0001), stabilizing at 8.5 months from implantation. Immediate mandibular implants had lower MBL (p = 0.0365). Post-loading, MBL was lower in the mandible (p = 0.0095) and positively influenced by abutment height and rotational abutments.

Conclusions: The present study supports the clinical efficacy of the IDIs placement protocol with high survival rates and acceptable MBL. It is recommended to place bone level implants slightly below the crest to ensure the platform remains at an optimal depth during the initial bone remodeling phase post-implantation.

即刻种植牙的边缘骨丢失及相关因素：回顾性临床研究。

目的：本研究的目的是在长达36个月的随访期间评估即刻种植体（IDIs）的边缘骨丢失（MBL），以及各种临床变量对MBL的影响。方法：对两个手术阶段放置的IDIs进行评价。种植体分为骨丢失（BL，露丝）、骨重塑（BR，种植体缘±0.1 mm嵴骨）和骨重叠（BO，基台以上骨）。结果：344例患者共植入idi 1040个，骨整合成功率为98.9%。平均MBL在2、6、12、24、36个月- 0.3±1.0毫米,1.1±-1.8毫米,- 1.4±1.8毫米- 1.7±1.9毫米- 1.3±2.3毫米,分别。在基线12个月期间，17.5%的idi患者出现BL， 9%出现BR， 73.5%出现BO。在B1-12个月期间，19.8%为BL， 10.7%为BR， 69.5%为BO。结论：本研究支持IDIs放置方案的临床疗效，具有高生存率和可接受的MBL。建议将骨水平种植体放置在略低于嵴的位置，以确保在种植后的初始骨重塑阶段平台保持在最佳深度。
