A crack in an implant-supported provisional arch needs a record of where the structure broke and an assessment of the supporting assembly. "The temporary broke" does not distinguish an artificial tooth, a connector or a joint at an abutment. Those distinctions matter when deciding what a repair should accomplish.
Contact the treating team promptly and avoid continuing to load the damaged area while waiting for their instructions. Do not use household glue or tighten exposed screws. Save any loose piece. If a component is missing and may have been swallowed or inhaled, use the separate guidance on a missing implant part. Breathing difficulty requires emergency help.
A 2026 series separated implant and prosthesis outcomes
A 2026 retrospective study followed ten selected patients receiving immediate short-arch maxillary restorations on four anterior implants. None of the 40 supporting implants failed during the reported follow-up, but five patients experienced fractures of the interim resin prostheses. The fractures occurred between 5 and 16 months, in distal cantilever regions, principally at connector or pontic areas. The prostheses had no metal framework reinforcement.
This was a small series of a particular staged treatment approach, with extended interim service. It does not give a fracture rate for all immediate full-arch designs. Its separate reporting of implant survival and prosthetic fracture is especially useful: success of one component does not erase a complication in another.
An earlier eight-patient case series of simultaneous bimaxillary immediate loading also reported prosthesis fractures, around three months, in patients identified as having bruxism. The abstract additionally reported implant failures. It cannot establish that a broken provisional is harmless or that bruxism is the only possible cause.
A fracture map to send before the visit
Photographs can help the team prepare, but they do not establish implant stability. Do not remove the restoration to obtain a better view. Describe what you can observe without manipulating it.
| Observation | Detail to record | Leave for assessment |
|---|---|---|
| Location | Tooth region and whether the break reaches the edge of the arch | Which structural element failed |
| Timing | Delivery date, first noticed damage and prior repairs | Whether service duration contributed |
| Event | What was happening when noticed. Say if no event is recalled | The cause of the fracture |
| Change | New movement, bite change, discomfort or a missing piece | Condition of screws, abutments and implants |
Keep the damaged area and its description linked to the same photograph. If a repair has already been done elsewhere, request its written record. A second fracture beside an old repair needs an accurate history, rather than an assumption that it is the same event recurring.
What the repair review should resolve
Ask whether the proposed work restores the existing design or changes it. If the team plans a redesign, the explanation should identify the constraint it addresses: the fractured region, the prosthetic material or a finding from the examination. The cited series does not supply a safe cantilever length or a universal reinforcement prescription.
Request a separate account of the support assessment. A structurally repaired provisional and an accepted implant-abutment assembly are different entries in the treatment record. Neither should be implied solely by the other.
Review the remaining provisional phase
Record the expected next stage and who will review the restoration if that stage is delayed. An interim that remains in service longer than planned deserves a discussion of the actual maintenance plan. Ask for the current eating and reporting instructions in writing.
When bruxism is part of the history, discuss the guard and repair maintenance record. That discussion complements the investigation of this fracture's location. It does not replace it.
