DEFINITION According to The Glossary of Prosthodontic
Terms, A provisional prosthesis is a prosthesis
designed to enhance aesthetics, provide stabilization and/or function for a limited period of time, and should be replaced by a definitive prosthesis after a period of time.

FUNCTIONS Provisional restorations can be used as a
diagnostic restoration. Used to preserve the soft tissue morphology
around extraction socket . Guide the healing of the peri-implant tissue. Gives information about shade, crown & soft
tissue contours.

It allows restoration of the integrity of the dental arch.
Occlusal stability of the opposing arch. Masticatory function. Proper speech and esthetics. Allows the patient to visualize and evaluate
the end restorative result.

REQUIREMENTS It should be rigid and have sufficient strength
to with stand the occlusal forces. Provide ideal environment for healing. It should restore normal intra oral function. It should function as a template for the
esthetics It should not exert pressure on surgical site.

Pre-operative radiograph. The patient had generalized refractory periodontitis, especially in the maxillary arch.
Pre-operative facial view. One of the patient’s chief complaint was the anterior crowding and the vertical drifting of maxillaryanterior teeth.

Diagnostic wax up of the planned restoration illustrating anticipated contours of the final restoration. The alignment of anterior teeth was altered to provide straighter, more aesthetically pleasing teeth. The incisal lengths of maxillary incisors were reduced, decreasing the horizontal and vertical relationship of the anterior teeth.
Facial view of prepared teeth immediately after extraction. Strategic teeth were maintained to retain the provisional prosthesis. The implant sites were previously selected and the non-strategic teeth were removed according to the diagnostic wax up.

Provisional acrylic restoration prior to insertion. The provisional restoration is relined with compatible self cure resin to fit over the prepared abutment teeth.
Fixed provisional restorations cemented on strategic natural abutments. The molars have been retained temporarily to maintain the vertical dimension of occlusion.

34
In extended partial edentulous areas where there are no or limited natural abutments to support a provisional restoration, one or more transitional implants may be used.
These transitional implants are loaded immediately to support the provisional restoration

35
Immediate provisional implants were placed and strategic teeth were maintained to support long-term telescopic provisional restoration. The 14-year-old patient requested a long-term fixed provisional restoration until the definitive implants are placed.

The term “immediate restoration” is used when a prosthesis is fixed to the implants within 48 hours without achieving full occlusal contact with the opposing dentition.
whereas “immediate loading” is when the prosthesis is fixed to the implants in occlusion within 48 hours.

Patient’s existing complete mandibular denture was modified to accommodate temporary cylinders on the implants. A duplicate of the denture was used as radiographic and surgical guide for the planning and surgical phase of the treatment. The three dimensional positions of the implants were determined from the diagnostic wax up and clinical and radiographic examination.
Try in of the mandibular denture over the temporary cylinders.

41
Self cure resin was used to attach the denture and the temporary cylinders. The denture flange was then trimmed and the fitting surface was adjusted to allow proper hygiene.
The provisional hybrid was used as verification jig over the master cast. The soft tissue moulage was removed to verify the fit of the provisional on the subgingival implant restorative margins

A cement on, prefabricated abutment was torqued to the recommended value, six weeks post-placement. The abutment Was chosen to allow adequate space for crown construction within the available interocclusal space.
A denture tooth with appropriate shade and shape was selected to fit the edentulous space. The acrylic tooth was then hollowed out to fit over a practice implant analog and abutment extra-orally.

45
The denture tooth was relined intra-orally using self cured acrylic resin to capture the indexing component of the abutment.
The relined denture tooth was fitted over the practice implant extra-orally. Note on the deficiency from the implant margin to the acrylic tooth due to tissue impingement.

The deficiency was filled in and the excess material trimmed to the appropriate emergence profile.
The provisional crown was cemented with provisional cement.

A temporary meso abutment, one piece temporary abutmentfits directly into the implant body. The abutment is made of PEEK(Polyetheretherketone) plastic and titanium inlay.
Unaltered temporary meso abutment on the soft tissue working cast. The abutment can be prepared in the laboratory or chair side with altered cement margin and corrections of anyangulation problems.

Long guide screws have been fitted on the two central implants and the temporary bridge seated intra-orally on its prosthetic carrier. The proper positioning of the guide screws (centrally through the bridge abutment openings) confirms that both the surgical and prosthetic stages have been accurately executed.
The four temporary cylinders have been tacked into position in the mouth. The bridge has been removed for final chair side acrylic additions and finishing.
