Can keeping a tooth fragment save your jawbone after an implant?

Summary

This trial tests whether a technique called socket-shield, which leaves a small piece of the natural tooth root in place, can better preserve bone and gum tissue around a new dental implant compared to the standard method. Adults aged 20-60 who need a front tooth replaced will be randomly assigned to receive an implant using either technique. Over 9 months, researchers will measure bone density, bone levels, and gum health to see which approach offers better outcomes.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance: Socket-shield technique (retaining a root fragment) compared with conventional immediate implant placement
What this could lead to: If successful, this could point toward a better way to place dental implants that preserves more bone and gum tissue, potentially improving long-term implant stability and appearance.
What could go wrong: This is a small, early-stage trial with only 16 participants, so results may not apply broadly. The socket-shield technique carries risks such as infection, root fragment complications, 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: * Patients aged between 20 and 60 years of both genders * All participants should be systemically healthy, as assessed using the dental modification of the Cornell Medical Index. * Gingival and periodontal health to be confirmed according to the criteria outlined in the new classification system proposed by Caton et al. (2018). * Presence of non-restorable teeth due to trauma, complicated crowns or root fractures. * Presence of extensive destructive caries making the tooth unsalvageable, particularly in esthetic zones. * Clinical indication for immediate implant placement, especially in cases where minimizing post-extraction bone resorption and soft tissue collapse is critical. * Availability of adequate interocclusal space to accommodate the necessary prosthetic components without occlusal interference. Exclusion Criteria: (for socket-shield technique) * Pregnant female. * Patients with parafunctional habits (e.g., bruxism, clenching). * Smokers. * Teeth with clinical mobility. * Teeth with root fractures extending below the alveolar bone level. * Periodontal ligament space widening. * Signs of internal or external root resorption. * Current or previous periodontal disease
