INTRODUCTION
According to M.M. Devan,
Stressing the importance removable partial dentures before the patient is
rendered edentulous ,
“A smooth uneventful transition not only results in a better denture
foundation physically and physiologically by maintenance of
normal neuromuscular patterns, but also psychologically, such a
transition diminishes the feeling of toothlessness”.
DEFINITIONS
Acccording to Heartwell,
A dental prosthesis constructed to replace the lost dentition and associated
structures of the maxillae and /or mandible, and inserted immediately
following removal of the remaining natural teeth.
According to GPT 9,
A complete denture or a removable partial denture fabricated for
placement immediately after the removal of natural teeth.
REVIEW OF LITERATURE
First described by Richardson in 1860.
1965- Heartwell, C and Salisbury F.W. presented an evaluation of immediate
complete dentures regarding requirements, diagnosis, advantages,
disadvantages and surgical preparation.
1968 - Campagna S.J., described an impression technique for immediate denture
fabrication.
Frank C. Jerb, described the technique of trimming the cast
for immediate denture.
According to him, it is based on anatomic factors and
positional changes that take place in gingival tissue when
teeth are extracted. Considerations must be given to existing
alveolar bone level as well as relative levels of the over lying
soft tissue structures.
1981 - Passamonti et al: determined the changes that take place in
maxillomandibular relations during a 3-month period following insertion
of immediate dentures. The results were as follows:
1.In the centric occlusion, the mandible moved forward at one week and
remained in that position for the three-month period.
2.The rest position remained relatively constant .
3.VDO and VDR showed a gradual decrease over the period.
4.Reline procedure did not affect the trend of the dimensional changes.
1990- Gardner et al.described a technique for obtaining the labial
section of an impression for a maxillary immediate complete denture.
1991- Tallgren ET. Al.: studied the gradual changes in the skeletal and soft
tissue profile of complete denture wearers resulting from residual ridge
reduction. They concluded that ridge resorption is most rapid during the first
half year and denture relining with correction of vertical dimension of
occlusion is indicated.
1992 - Gary R. Goldstein: presented an alternative immediate complete
denture impression technique for mobile teeth, which have the possibility
of being extracted at the time of impression making.
1992 - Zafrulla Khan: presented a technique for one appointment
construction of an immediate transitional denture using VLC resin.
2000 - William C. Elton: presented a method to confirm the intaglio
surface of an immediate complete denture when using a chair side soft
reline procedure after tooth extraction.
REQUIREMENTS OF IMMEDIATE COMPLETE DENTURE
John J. Sharry: Complete denture prosthodontics 3
rd
Edition
PHYSICAL FACTORS:
1) Disuse atrophy of the bony base
2) Unfavorable healing of the repairing bone
3) Possible damage to the ligaments surrounding TMJ
LaVere,A.M. & Krol.A.J.: Immediate denture service. JPD 1973,29,10-15.
PHSYIOLOGICAL REASONS
1.Abnormal functioning of the mouth and mandible
2. Impaired communication
3. Abnormal deglutition
PSYCHOLOGICAL REASONS:
1.Adverse subjective reactions
LaVere,A.M. & Krol.A.J.: Immediate denture service. JPD 1973,29,10-15.
CONTRAINDICATIONS OF IMMEDIATE DENTURES:
•Demer, W.: Minimizing problems in placement of immediate dentures. JPD 1972,27,275-284.
ADVANTAGES OF IMMEDIATE DENTURE:
1)Prevent patient embarrassment: to those patients who are
never without natural teeth.
2)Promote patient health: prevent the prolonged retention of
diseased teeth that occur when patients avoid tooth removal.
3)Provide guide for optimal esthetics: The form, size, color and
arrangement of natural teeth can be reproduced.
ZARB, BOLENDER – Prosthodontic treatment for edentulous patients 12
th
edition.
4)Provide guide for occlusal vertical dimension: through contact with
teeth in the opposite arch or observation of closest speaking space.
5)Preserves diet and nutrition : spared the inconvenience and distress of
inability to masticate food and inevitable nutritional compromise.
6)Promote better healing : act as surgical stents by applying pressure to
soft tissue to facilitate healing and to prevent cicatrisation or tissue
collapse.
ZARB, BOLENDER – Prosthodontic treatment for edentulous patients 12
th
edition.
7) Promote better ridge form: Subjecting the healing tissue to functional
denture forces within physiological limits results in a better form.
8)Prevent collapse of facial musculature: When the lips and cheeks have
not altered their positions because of the lack of tooth support, it is less
difficult to obtain esthetic harmony and functional compatibility.
9)Hasten patient adaptation to Dentures: immediate transition from
some natural teeth to dentures makes the adjustment to speaking and
eating with dentures much less difficult.
ZARB, BOLENDER – Prosthodontic treatment for edentulous patients 12
th
edition.
a) Conventional immediate dentures:
Posterior teeth are removed and wait a minimum of 3-6 week healing period
before making dentures.
b) Transitional immediate dentures:
Replaced by a conventional denture immediately after extraction.
c) Diagnostic denture:
It is useful for diagnostic purposes in cases of advanced periodontal disease with
mobility where vertical dimension of occlusion and centric relation are
difficult to determine.

“Jiffy’s dentures”
Type of intermediate immediate dentures
Introduced by Raczka and Esposito in 1995
Denture teeth are made in tooth colored acrylic resin
Main disadvantage is that the materials used in its fabrication are not long
lasting.

TREATMENT PLANNING:
Two-phase tooth removal simplifies clinical procedures, reduces post
placement care and improves denture comfort, retention and stability.

Final Impression Techniques For Immediate Dentures
•Lambrecht.J.R. : Immediate denture construction: the impression phase. JPD 1968,19,237-240.
1) Single Full arch custom impression tray :
Utilizes custom auto polymerizing resin trays made over a cast with a
wax spacer.
A tripod stop effect is established on the incisal edges of the remaining
teeth anteriorly and in the posterior palatal seal and buccal shelf areas
posteriorly.
ZARB, BOLENDER – Prosthodontic treatment for edentulous patients 12
th
edition.
2) Two – tray or sectional custom impression tray:
Custom trays are made to conform to the edentulous segments only.
Sectional impression made and checked ,excess material removed and
replaced in the mouth.
A perforated stock tray that will accommodate the anterior teeth and the
sectional impression is selected and pick up impression is made.
ZARB, BOLENDER – Prosthodontic treatment for edentulous patients 12
th
edition.
3) Campaqna Impression Technique:
This technique uses a open custom tray with a labial flange.
Opening :3-4 mm from gingival margins of the remaining teeth.
Border molding and impression making is done
Trim the excess material and replace in mouth back.
Select a stock tray that fits over the remaining teeth and custom impression
tray and make a pick up impression
LCampagna, S.J.: An impression technique for immediate dentures. JPD 1968,20,196-203
4)Split impression technique :
A preliminary impression compound impression is made.
The entire labial portion from the incisal edges of the teeth upward is cut.
Impression plaster is introduced over the labial surface of the teeth and
mucosa to complete the impression.
When set, the plaster section is
fractured , the palatal section is removed
and the two are again reassembled.

JAW RELATION FOR IMMEDIATE DENTURES
VR before extraction : Premolars with no attrition or mobility.
Natural mandibular teeth : Guide to establish the occlusal plane
If anterior teeth in arch occlude against six anterior teeth in arch: Do
not rely on their occlusal relations for vertical dimension.
When a vertical overlap cannot be reproduced : Ignore and consider only
the interarch space between occlusal rims for correct VR.

JAW RELATION AND TEETH ARRANGEMENT
Occlusal rims are tried in patients mouth.
Existing Vertical dimension is evaluated
Occlusal rims are trimmed to the desired VD
Centric relation is recorded
Face bow transfer and mounting

ARRANGEMENT OF THE ANTERIOR TEETH
Objective : Position necks of artificial teeth as close to natural anteriors.
Severe labial undercuts dictate need for an extensive alveolectomy if a
conventional denture outline is used.
Short labial flanges: To avoid need for extensive removal of alveolar bone.
If no alveolectomy is planned, the marginal gingival portion of cast should
be cut back at cervical area until in level with labial surface.

CONCLUSION
Immediate dentures fulfill an important role in today's treatment
modalities by providing the patient with esthetics, function &
psychological support after extraction & during healing phase.
The technique is more demanding than conventional complete
denture for both patient & operator as well.
If the patient is prepared & appropriate type of immediate denture
is selected the resulting prosthesis can be a success.
