3D‑printed mucocompressive stent with suture‑anchors: a simple way to protect keratinized mucosa grafts in reconstructed jaws

A small prospective proof‑of‑concept shows a customised 3D‑printed stent plus suture‑anchors can hold a free epithelial graft in place, give a large immediate keratinized band and preserve vestibular depth with modest shrinkage at 12 weeks.

Why this matters: inadequate keratinized mucosa (KMW) and shallow vestibules make hygiene and long‑term maintenance around implants harder. Systematic reviews and consensus statements recommend assessing KMW routinely and, when clinically indicated, increasing it with autogenous grafts or reliable substitutes to improve tissue stability and patient comfort.

What the new report did: a 2026 prospective single‑cohort proof‑of‑concept enrolled four patients with mandibular reconstruction using free fibula flaps; the team used an interim implant‑supported prosthesis plus a custom 3D‑printed mucocompressive surgical stent and a suture‑anchor system during apically positioned flap/vestibuloplasty and a free epithelial graft. The cohort included 17 implants; outcomes were measured immediately, at 4 weeks and at 12 weeks. ([eurekamag.com](

Key results in plain language: mean keratinized mucosa width rose from essentially zero (0.14 mm) before surgery to 5.40 mm immediately after the procedure, then to 4.82 mm at 4 weeks and 4.07 mm at 12 weeks — an overall shrinkage of about 24% from the immediate postoperative measurement. Vestibular depth increased from 0 mm to about 8 mm immediately and remained clinically deep at follow‑up. Sites that used suture‑anchors showed significantly less KMW shrinkage and less vestibular recession than non‑anchored sites. Postoperative pain was mild and brief. ([eurekamag.com](

How to interpret those numbers: free gingival/free epithelial grafts commonly undergo notable contraction in the weeks and months after surgery; published trials report a wide range of shrinkage (commonly 20–45% at 3 months and larger reductions at 12 months depending on technique and material). The 24% shrinkage at 12 weeks in this report sits within the lower midrange of published shrinkage figures, while the large immediate gain and preserved vestibular depth are the clinically useful points. The anchored stent appears to reduce early contraction in this small series. ([aap.onlinelibrary.wiley.com](

What this means for your chair on Monday: if you manage peri‑implant soft tissue problems after reconstruction or where graft stability is difficult, a compressive stent that immobilises the graft and maintains vestibular depth can be helpful. You don't need an industrial CAD/CAM lab to start: many dental labs or basic in‑office printers can produce a simple mucocompressive plate from a scanned interim prosthesis; suture‑anchors (all‑suture anchors or small bone anchors) can give mechanical fixation on the buccal side and appear to reduce shrinkage. Use the stent as an adjunct to established surgical steps (apically positioned flap / vestibuloplasty + FEG or FGG). ([eurekamag.com](

Practical checklist and tips: (1) plan the stent on the interim prosthesis to compress the graft uniformly and avoid pressure points; (2) place suture‑anchors where you can engage soft tissue or thin cortical bone safely and avoid damaging implants; (3) expect early shrinkage — aim for an immediate KMW that is comfortably larger than your target so residual width sits around 2–3 mm at healing; (4) monitor for hematoma/infection and remove stent on schedule so you do not trap exudate. The 3D stent is a stabiliser, not a substitute for meticulous graft technique. ([eurekamag.com](

Limitations and next steps: this is a very small (4‑patient, 17‑implant) cohort with short follow‑up (12 weeks) and no control group. The technique was used in reconstructed mandibles where soft‑tissue conditions differ from routine cases. Larger controlled trials and longer follow‑up are needed to show whether the stent + anchor combination beats standard fixation methods or biomaterial substitutes for long‑term stability. In the meantime, view it as a pragmatic option for difficult cases where graft immobilisation is the main challenge. ([eurekamag.com](
