Cheaper sinus lift for dental implants? gelatin sponge tested against bone graft
NCT ID NCT06681857
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This completed trial tested whether a gelatin sponge works as well as a bone matrix for lifting the sinus floor during dental implant placement. Fourteen patients with low bone height in the upper jaw received one of the two materials. The study measured bone gain and implant stability over six months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- gelatin sponge and allogenic demineralized bone matrix
- What this could lead to
- If gelatin sponge works as well as bone matrix, it could offer a cheaper, simpler option for sinus lifts during dental implants.
- What could go wrong
- This is a very small trial (14 people) with no phase, so results may not apply broadly. Both methods carry risks like infection or implant failure.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patients of both sexes, with an age range of (25 to 55 years) with unilateral or bilateral edentulous posterior maxillary molar region with \\ vertical residual bone height of (four to six millimeters), a minimal horizontal bone width of six millimeters bone width, acceptable interarch space, and fair inter-jaw anteroposterior, horizontal and vertical relationships. 2. Proper general health and oral hygiene. Exclusion Criteria: 1. The presence of sinusitis, local sinus pathosis, or a systemic disease that would affect the final treatment outcomes, bone remodeling process, or maxillary sinus health. 2. Those patients with a history of previous bone graft, sinus lift, or failed implant.
