Deep overbite is one of the most common malocclusions and is the most difficult to treat successfully. The real challenge remains the stability of long-term deep overbite correction. A search through the scientific literature revealed only one systematic review on this subject. Given the recent publications on the stability of deep bite correction and the development of new processes designed to avoid relapse of these treatments, this one existing systematic review needs to be updated. The purpose of the present systematic review is to evaluate the long-term stability of deep overbite correction.
Electronic databases were searched and nonelectronic journals were manually explored for papers on long-term stability and relapse of deep overbite correction. Articles deemed appropriate for inclusion in this review were selected and analyzed. Their scientific quality was assessed and the data they contained were extracted and summarized.
The rate of deep overbite relapse was 47.27%. Patients treated with the straight wire appliance showed a 67.74% relapse rate whereas those treated with the Ricketts biological progressive segmented mechanics appliance displayed a 30.38% rate. Subjects treated towards the end of adolescence presented a 14.3% rate of deep overbite relapse whereas those treated in their early teens or in adulthood had a deep overbite relapse rate of 30% and 30.8%, respectively. Intramuscular injections of botox helped obtain 100% stability in maxillofacial surgery to correct deep bite.
Age at initiation of treatment and treatment technique are two factors impacting the long-term stability of deep overbite correction.
深覆合是最常见的错牙合畸形之一，也是最难成功治疗的。真正的挑战仍然是长期深覆合矫正的稳定性。查阅科学文献发现，关于这个主题只有一篇系统评价。鉴于最近有关深覆合矫正稳定性的出版物以及旨在避免这些治疗复发的新方法的发展，这篇现有的系统评价需要更新。本系统评价的目的是评估深覆合矫正的长期稳定性。
检索电子数据库，并人工查阅非电子期刊，以查找有关深覆合矫正长期稳定性和复发的论文。选择并分析了被认为适合纳入本评价的文章。评估它们的科学质量，并提取和总结其中包含的数据。
深覆合复发率为47.27%。使用直丝弓矫治器治疗的患者复发率为67.74%，而使用Ricketts生物渐进分段力学矫治器治疗的患者复发率为30.38%。在青春期后期接受治疗的受试者深覆合复发率为14.3%，而在青少年早期或成年期接受治疗的受试者深覆合复发率分别为30%和30.8%。在颌面外科手术中，肌肉注射肉毒杆菌毒素有助于获得100%的稳定性以矫正深覆合。
开始治疗的年龄和治疗技术是影响深覆合矫正长期稳定性的两个因素。
