Plaque and gingival bleeding were scored and probing, radiography, and histologic methods were used to evaluate clinical methods for estimating alterations of supporting structures at functioning endosseous dental implants. Twelve implant abutment posts in three Labrador retriever dogs were assessed. The observation period was 3 months of submerged healing followed by 6 months in function. In the presence of daily gingival cleaning, both plaque and gingival bleeding scores were reduced on implant abutments. No correlation was found between gingival scores and the degree of bone resorption. The correlation between probing and radiographic measurements was studied by comparing 136 parallel measurements. The average difference was 0.4 mm. Discrepancies were observed when evaluating bone loss that reached the shoulder area. Better accordance was obtained when moderate (2 to 4 mm) or extensive (6 to 8 mm) resorption was assessed. Histologic evaluation indicated alternating regions of implant-bone contact and fibrous encapsulation. Progressive infiltrates were observed in the permucosal area, sometimes extending into the deeper parts of the supporting bone. A combination of probing and radiographic measurements seems to give the most reliable information about the level of bone support and is recommended to be included in routine control of implant abutments.
对菌斑和牙龈出血进行评分，并采用探诊、影像学检查和组织学方法，评估用于估计功能性骨内牙种植体支持结构改变的临床方法。对3只拉布拉多寻回犬的12个种植基台进行了评估。观察期为3个月的埋植愈合期，随后是6个月的功能期。在每日进行牙龈清洁的情况下，种植基台上的菌斑和牙龈出血评分均降低。未发现牙龈评分与骨吸收程度之间存在相关性。通过比较136次平行测量，研究了探诊与影像学测量之间的相关性。平均差异为0.4毫米。在评估到达肩部区域的骨丢失时观察到差异。在评估中度（2至4毫米）或广泛（6至8毫米）吸收时，一致性更好。组织学评估表明种植体与骨接触区域和纤维包囊交替出现。在黏膜下区域观察到进行性浸润，有时延伸至支持骨的深部。探诊和影像学测量相结合似乎能提供关于骨支持水平的最可靠信息，建议将其纳入种植基台的常规检查中。
