Introduction
 Squamous cell carcinoma of the oral cavity is the malignant
neoplasm that makes individuals suffer both physiologically and
psychologically
 Surgical resection of the tumour and the structures involved with
it along with the radiotherapy or chemotherapy is the treatment
protocol for oral squamous cell carcinoma
 It is very difficult to do the prosthetic rehabilitation of such
patient especially for the mandible because the segmental loss
of mandibular integrity leads to its deviation towards the
resected area with lack of occlusion
 In addition segmental loss of mandible results in limited mouth
opening
Aim and Objectives
 This case report deals with Cantor and Kurtis type two defect in
which mandible was resected distinctly from canine region on the
right side of the Arch
 In this report the patient was rehabilitated with a double occlusal
table
Cantor and Curtis defect classification
Class 1 – Radical Alveolectomy
With preservation of
mandibular continuity
Class 2- Lateral resection of the
mandible distal to the canine
area
Class 3 – Resection of the
mandible to the midline
Class 4 – Lateral resection surgically reconstructed
with bone grafts
Class 5- anterior mandibular defects with bone graft
reconstruction
Class 6- anterior man develops without surgical
reconstruction
Case presentation
 43 years old male patient
 Chief complaint- Compromised
aesthetics, difficulty in speaking, lack of
ability to chew
 Extraoral examination- Mandibular
deviation on the right side compromising
the aesthetic
 Intraoral examination- maxillary Kennedy
class one partially edentulous arch
 Patient was habitual eating beetle nuts
for past eight years
Treatment planning
 Primary impression was made using alginate
 Secondary impression was made using addition silicon
 Master cast was obtained on which fabrication of Wax
occlusal rims was done
 Jaw relation was performed
 The retention in the presented case was provided by
the circumferential clasps on the abutment teeth 12
and 25
 The two rows of semi anatomic acrylic were selected
 The Edentulous Spaces were replaced by first row of
anatomical teeth in the desired position and the second row
was arranged on the palatal to the first row where mandible
watch closing in a functional position
 Follow up was done regularly
Discussion
 The rehabilitation of mandible defects are challenging
because in addition to the loss of anatomical structure there
is also loss of sensation of muscles of mastication and
occlusion
 Phonetics is also important parameter in achieving normal
physiological activity of the patient
 Pronunciation of various words sounds should be accurate
 The benefit of this prosthesis is cost effective patient friendly
and light in weight to withstand the force of gravitation
Conclusion
 The rehabilitation of Hemi mandibulectomy patients with
double occasional table prosthesis its efficacious and is of
considerable importance
 This report gives a productive plan to give a prosthesis in
the Maxilla when there is limited space left in the
mandibular arch
 However clinical techniques complexity of the case
maintenance of the prosthesis and patient acceptance will
determine the treatment prognosis
