This review assessing the efficacy and morbidity of biodegradable vs. titanium osteosyntheses in orthognathic surgery included 33 studies 11 of which were RCTs. The findings suggest that biodegradable osteosyntheses is a valid alternative to titanium osteosyntheses for orthognathic surgery, but the quality of evidence is low.

16 RCTs were included in this Cochrane review update of the effectiveness of techniques for alveolar ridge preservation (ARP) following dental extractions prior to implant placement. The findings suggest that ARP techniques may minimise the overall changes in residual ridge height and width six months after extraction, but the evidence is very uncertain

This review of whether the incidence of osteoradionecrosis differed between patients who have dental extractions before or after radiotherapy (RT) included 24 studies (19 retrospective 5 prospective). While the findings suggest that the incidence is similar if extractions are undertaken before or after RT the quality of the evidence is limited.

This Cochrane review update of the effect of systemic antibiotic prophylaxis on the prevention of infectious complications following tooth extractions included 23 studies. There was very-low certainty evidence that prophylactic antibiotics may reduce the risk of infection and dry socket following third molar extraction compared to placebo.
