Tooth loss

This study tests a fully digital approach to placing and loading dental implants in people aged 65 and older who need a tooth extracted. Using 3D imaging and computer-guided surgery, the implant is placed and a temporary tooth is attached within 48 hours. Researchers will track i…

This trial tests whether a custom-made abutment placed immediately after tooth extraction helps preserve gum tissue around a new dental implant. Thirty adults needing a molar replaced will receive either a custom or standard abutment. Researchers will compare gum volume changes a…

This trial investigates whether adding a simvastatin and platelet-rich fibrin (PRF) composite to a standard bone graft improves bone regeneration during dental implant surgery. The study enrolls adults aged 18–50 with a narrow jawbone (3–5 mm wide) who need an implant in the lowe…

This study tested whether adding a bone growth protein (rhBMP-2) to dental implants placed right after tooth removal improves implant stability and preserves jawbone. Twenty-four adults with damaged upper front or premolar teeth received either the protein or standard implant pla…

This study looked at whether placing a dental implant right after pulling a tooth works as well as waiting for the gum to heal first. Fifty-three adults with a single missing tooth in the front or premolar area received a Straumann implant either immediately or after healing. Res…

This study tested different surface treatments on the metal base of dental implants to see which helps keep a zirconia crown attached best. Twenty-seven adults missing a lower molar received a crown, and the metal base was either left untreated, coated with silica, or coated with…

This study tested a new dental implant with a sloped neck against a standard implant that requires bone grafting. Forty adults needing a single tooth replacement were randomly assigned to one of the two groups. The goal was to see if the sloped design could maintain bone and gum …

Researchers at Cairo University are testing two methods for placing dental implants right after removing a molar. In one method, they drill through the bone between the roots before pulling the tooth, then place the implant. In the other, they remove the tooth first and place the…

This study followed 39 people who needed a tooth pulled and replaced with a dental implant. After extraction, the socket was filled with a bone graft material called Bio-Oss Collagen. Researchers then placed implants at 3, 6, or 9 months later to see how the bone healed over time…

This trial tests whether using just one guided drill (a pilot hole) followed by freehand drilling is as accurate as using a full set of computer-guided drills for placing dental implants. Researchers will compare the final implant position against the planned position using 3D sc…

This study compares two ways to place dental implants in the upper front teeth area: one that involves cutting and lifting the gum (flap technique) and one that does not (flapless technique). Sixteen adults who have been missing a tooth in that area for over a year will receive a…

This study looked at whether treating the healing caps placed on dental implants with cold plasma can reduce early bacterial buildup. Twelve people each received four implants, and each implant got a different plasma treatment or none. The healing caps were removed after one week…

This study looked at 60 people who needed dental implants for missing back teeth in the upper jaw. It compared three methods: using Densah burs, a magnetic mallet, or conventional drilling. The goal was to see which technique made the implant most stable right after placement, at…

This study looked at how inflammatory bowel disease (IBD) affects oral health and daily life. Researchers compared 138 adults with IBD to people without IBD, using a questionnaire to measure oral health-related quality of life. The goal was to understand which factors, like medic…
