Implants

Oral administration of two grams of amoxicillin one hour before placement of dental implants is effective in reducing implant failures. Unclear whether postoperative antibiotics are beneficial, or which antibiotics work best.

Weak evidence that flapless placement of dental implants reduces postoperative discomfort (pain and swelling).
Insufficient evidence to recommend any specific flap or suturing technique.
Insufficient evidence regarding soft tissue grafts from the palate improving gum thickness and aesthetics.
Insufficient evidence to determine which is the most effective way to treat peri‐implantitis.
Insufficient evidence to demonstrate superiority of any particular type of implant characteristic or implant system over another.
Insufficient evidence to determine the possible advantages or disadvantages of immediate, immediate-delayed or delayed implants
Various techniques can augment bone horizontally and vertically, but it is unclear which are the most efficient.
Insufficient evidence to determine when sinus lift procedures are needed.

Implants following radiotherapy
Insufficient evidence to determine the effect of HBO therapy in preventing failure of dental implants or other serious complications such as the death of bone in the jaw caused by radiotherapy treatment.

Dental prostheses
Insufficient evidence to determine whether one type of removable dental prosthesis (RDP) is better or worse than another.
With fixed dental prostheses (FDPs), there was no evidence that high gold alloys are better or worse than other alloys, nor that gold alloys or frameworks are better or worse than titanium.
Insufficient evidence to determine whether zirconia is better or worse that other FDP materials, that ceramic abutments are better or worse than titanium, or that one cement was better or worse than another in retaining FDPs.
Insufficient evidence to determine the relative effectiveness of FDPs and RDPs in patients with shortened dental arch or to determine the relative advantages of implant supported FDPs versus tooth/implant supported FDPs.

Avulsed teeth
Insufficient evidence regarding the management of Avulsed front teeth. However, available evidence suggests that extra‐oral endodontics is not detrimental for teeth replanted after more than 60 minutes dry time
