Recent data have shown that short dental implants can be the preferred treatment in most of cases of posterior atrophic alveolar ridges, offering higher survival and lower complication rates than long implants. The survival rates, stability, and marginal bone level changes were compared between short implants (7 and 8.5 mm) and standard-length implants (≥10 mm).
Prospective observational study in which adult patients requiring ≥1 osseointegrated implants to replace missing teeth were recruited consecutively. A clinical examination was performed on the day the definitive prosthesis was placed and after 6 and 12 months. Implant stability quotient (ISQ), marginal bone level (MBL) changes, and the correlation between these parameters and the characteristics of the implants were evaluated.
A total of 99 implants were inserted (47 short, 52 standard) in 74 patients. The 12-month survival rate was 100%. ISQ values showed a similar pattern for both types of implants. No correlation was found between ISQ changes after one year and MBL values, nor between the latter and the characteristics of the implants.
With clinical treatment criteria, shorter implants (7 and 8.5 mm in length) can be just as useful as standard-length implants in atrophic alveolar ridges, demonstrating similar rates of survival, stability, and crestal bone loss.
近期数据表明，在大多数后牙区牙槽嵴萎缩病例中，短种植体可能是首选治疗方式，其生存率高于长种植体，并发症发生率低于长种植体。比较了短种植体（7和8.5毫米）与标准长度种植体（≥10毫米）的生存率、稳定性及边缘骨水平变化。
一项前瞻性观察研究，连续招募需要≥1枚骨整合种植体来替代缺失牙的成年患者。在最终义齿植入当天、6个月和12个月后进行临床检查。评估种植体稳定性商数（ISQ）、边缘骨水平（MBL）变化以及这些参数与种植体特征之间的相关性。
74例患者共植入99枚种植体（47枚短种植体，52枚标准种植体）。12个月生存率为100%。两种类型种植体的ISQ值呈现相似模式。未发现一年后ISQ变化与MBL值之间、以及MBL值与种植体特征之间存在相关性。
根据临床治疗标准，较短的种植体（长度为7和8.5毫米）在萎缩性牙槽嵴中与标准长度种植体同样有用，显示出相似的生存率、稳定性和嵴顶骨丧失率。
