摘要/Abstract

摘要： 本文探讨伴牙周炎患者种植牙同期行引导性骨再生（GBR）技术治疗对牙槽骨吸收的影响。选取接受牙种植同期行GBR技术治疗的患者90例作为研究对象，其中伴有牙周炎的患者有42例（牙周炎组）、不伴有牙周炎的患者有48例（对照组），采用CBCT观察两组的牙槽骨参数并进行比较。负载2年后（T2），牙周炎组患者的牙槽骨近中点、远中点、舌侧的牙槽骨高度测定值[（2.64±0.09） mm、（2.66±0.13） mm、（3.91±0.16） mm]均低于对照组的[（2.76±0.13） mm、（2.72±0.11） mm、（3.99±0.18） mm]，且差异具有统计学意义（P<0.05）；牙周炎组患者的牙槽嵴顶区舌侧、牙槽嵴顶区唇侧、根尖区舌侧的牙槽骨密度值[（1054.1±97.6） Hu、（1058.3±113.0） Hu、（989.1±98.0） Hu]均低于对照组的[（1147.3±133.0） Hu、（1103.0±86.3） Hu、（1067.6±103.8） Hu]，且差异具有统计学意义（P<0.05）。与无牙周炎病史的患者相比，具有牙周炎病史的牙缺损患者接受牙种植同期行GBR技术治疗后种植体周围骨吸收更加的明显，CBCT技术能较好地观察到种植体周围骨吸收的情况。

Abstract: This study explored the effect of simultaneous guided bone regeneration (GBR) treatment on alveolar bone resorption in patients with periodontitis. Ninety patients who underwent GBR treatment during the same period of dental implantation were selected as the research objects. Among them, 42 patients with periodontitis (periodontitis group) and 48 patients without periodontitis (control group), using cone beam CT (CBCT) to observe and compare the alveolar bone parameters of the two groups. After loading for 2 years (T2), the measured values of the alveolar bone height of the proximal midpoint, distal midpoint, and lingual side of the periodontitis group[(2.64±0.09) mm, (2.66±0.13) mm, (3.91±0.16) mm] were lower than the control group[(2.76±0.13) mm, (2.72±0.11) mm, (3.99±0.18) mm], and the difference was statistically significant (P<0.05), In the periodontitis group, the lingual side of the alveolar crest area, the labial side of the alveolar crest area, and the lingual side of the apical area of the patients in the periodontitis group[(1054.1±97.6) Hu, (1058.3±113.0) Hu, (989.1±98.0) Hu] were lower than the control group[(1147.3±133.0) Hu, (1103.0±86.3) Hu, (1067.6±103.8) Hu], and the difference was statistically significant (P<0.05). Compared with patients without a history of periodontitis, patients with dental defects with a history of periodontitis received more obvious bone resorption around the implant after dental implantation and GBR treatment at the same time. CBCT technology can better observe the bone around the implant Absorb the situation.
