Objectives: After tooth extraction, remodelling of alveolar bone takes place, as widely described in the literature. Significant dimensional changes occur in both soft and hard tissues, compromising future treatment of the edentulous area, but socket preservation may counteract this process. The aim of this review was to identify evidence related to the technique of socket preservation. Methods: An electronic search of MEDLINE–PubMed and Cochrane Central was performed. The inclusion criteria were based on the type of study, namely randomised controlled clinical trials and controlled clinical trials with natural healing as the control, published in English between 2000 and 2015. Results: The selection phase yielded 1138 suitable publications from MEDLINE–Pubmed and Cochrane Central, of which 38 were screened. After applying the inclusion criteria, 15 articles describing randomised controlled clinical trials were included in the study. Analysis of these showed that natural healing groups had a reduction in width of –0.16mm to –4.3mm and –0.56 to –3.75 in height. In the test group, results ranged from –2.5mm to +3.5mm for width and –2.48 to +1.3mm for height. Hence, the percentage of vital bone ranged from 25.7% to 57.4% at 6 months; for sockets filled with Bio-Oss[tm], this was between 10.4% and 34.5% at 6 months, and for sockets filled with calcium sulphate, between 36.25% and 63.16% at 3 months. There was insufficient evidence to establish the superiority of one biomaterial or technique above the other. Conclusion: According to analysis of the available literature, the alveolar preservation technique is associated with less vertical and horizontal bone loss than control methods.
