Planning a Full Mouth Case.
A full mouth reconstruction is a treatment plan carried out over months. The restorations are the last part and the least likely to be where it goes wrong.
Diagnose why the dentition failed
Before deciding what to build, establish what destroyed what was there. Attrition from parafunction, erosion from dietary or gastric acid, abrasion, caries, periodontal collapse, or a combination — each has different implications and each will continue after treatment if it is not addressed.
Restoring an eroded dentition without managing the acid source produces the same pattern of destruction around new restorations. Restoring a bruxing patient without protection transfers the fracture from teeth to ceramics.
This is the step most often compressed, and it is the one that determines whether the reconstruction lasts a decade or three years.
Gather records that support planning
A full photographic series covering retracted views, occlusal views, the smile and the face. Mounted study casts, with a facebow record so the articulator approximates the patient's condylar geometry rather than an average. Full radiographic assessment, with CBCT where implants or endodontic questions are involved. A periodontal chart.
These are not administrative. They are the material from which the plan is made, and a plan made without them is being made from memory and impression.
The diagnostic wax-up follows from them, and it is worth doing properly. It is the first physical statement of what the case is trying to achieve, and it is what everything afterwards is measured against.
Decide the vertical dimension deliberately
Where wear has been substantial, the space needed for restorations does not exist at the patient's current closure, and creating it by reduction alone would destroy what remains.
Increasing the vertical dimension creates space across the whole arch at once. It requires assessment of freeway space, of the patient's existing muscular comfort, and of phonetics, and it must be tested before it is committed to.
The literature is generally reassuring about patients adapting to moderate increases, but adaptation is not universal and it is not predictable from measurement alone. The provisional phase is where it is established, not the articulator.
Sequence: stabilize, provisionalize, restore
Stabilization comes first — caries control, endodontic treatment, periodontal therapy, extraction of teeth that are not salvageable. Building definitive restorations onto an unstable foundation is the most expensive mistake available in this kind of case.
The provisional phase follows, and it is where the plan is tested: the vertical dimension, the occlusal scheme, the incisal edge position, the tooth proportions and the patient's tolerance of all of them.
Definitive restorations come last, and by then very little should be uncertain. If the provisional phase has done its job, the definitive stage is reproduction rather than design.
The provisional phase is the case
Provisionals here are not temporary coverings. They are a full-mouth prototype worn for weeks or months, adjusted in response to how the patient functions, and evaluated for comfort, appearance, phonetics and stability.
Adjustments made during this period are the real design. A patient who has worn a provisional scheme comfortably for two months has demonstrated something no articulator can predict.
Record the provisionals once they are working — scans, impressions, photographs and a mounted set — and send that record with the definitive case. The instruction to the laboratory is to reproduce the provisional, not to reinterpret the original wax-up.
Material strategy across the arch
It is rarely correct to use one material everywhere. Posterior units in a bruxing patient want strength; anterior units want optical performance; abutments under partial dentures want metal.
What matters is coherence. Adjacent units in different materials at the same nominal shade will not look identical, so material changes should be placed where they are least visible — typically at the canine or first premolar.
Whatever the strategy, it should be decided across the whole case at the outset rather than tooth by tooth as each is prepared.
Protect what you have built
If parafunction caused the original destruction, it has not been treated by restoring the teeth. An occlusal splint worn nightly is usually the single most cost-effective element of the whole plan, and it should be presented as part of the treatment rather than as an optional extra afterwards.
Build it into the fee, the consent discussion and the review schedule from the beginning. A patient told at the end that they now need a splint tends to hear it as an additional charge rather than as protection for a substantial investment.
Be realistic with the patient
Time, cost, number of appointments and the interim appearance all need stating plainly at the outset. Patients tolerate a long treatment they understood in advance; they do not tolerate one that keeps extending.
It is also worth being explicit that reconstruction is maintenance-dependent. These cases need review, they need the splint worn, and they need components repaired or replaced over their life.
A patient who understands that from the start becomes a partner in maintaining the work. One who believed it was finished at delivery does not.
Involve the laboratory early
Full mouth work is the least suitable category for a prescription written at dispatch. The technician needs to understand the plan, the vertical dimension decision, the occlusal scheme and the material strategy before anything is made.
A conversation at the planning stage, with the wax-up and the records to hand, is worth more than any volume of written instruction later.
In short
- Diagnose the cause of destruction before planning the restoration
- Mounted casts with a facebow and a diagnostic wax-up are the planning material
- Test any vertical dimension change through provisionals, not on the articulator
- Record the working provisionals and instruct the laboratory to reproduce them
- Present the protective splint as part of the treatment, not an afterthought
