An Autogenic Transplantation

4.  What is “A.D.T”?
“Autogenic Dental Transplantation can be defined
as,
“the transplantation of a tooth from one
position to another in the same indivdual.”
Source-Dental Dictionary-Mosby

5. Where to do ??...
• transplantation of impacted teeth to their normal position trans-
alveolar transplantation)
• agenesis of teeth (congenitally missing teeth ),
• avulsion where the prognosis for successful re-implantation is
poor,
• untreatable root fractures.

• other prosthetic reconstructions may cause delayed aesthetic or
functional problems.

7. At the recipient site-
Placement should be deep into the socket
soft tissues sutured around it.

8. Fixation should be flexible using resilient wires or by customized
orthodontic appliances.
rigid fixations-contraindicated-they lead to ankylosis and
resorption of the tooth.

Bjercke , in 1974
& 1978
respectively,
documented a 100%
success rate for 34
autogenic
transplantations
of premolars

10.  Prognosis -depends on-
-surgical technique
-skill
-patient’s concern.

11.  Preoperative factors-
 Patient age
 stage of development
the tooth.  Peroperative factors-
 shape of the roots,  surgical trauma
 relative dispensability  storage after
of tooth extraction of tooth

Premolars
Third molars.

13.  Fully developed donor teeth,
 r oot canal
treatment-initiated 2 weeks after
transplantation.
 Donor tooth with incomplete root formation-
 p reservation of the apical Hertwig's epithelial root
sheath to ensure
 p ulpal regeneration and
 r oot maturation and eruption.
 Ideally,
D onor tooth should be of maximum length and having its potential for pulp
regeneration

14.  Comparison Of Auto Transplants with Dental
Implants
 Auto
Transplant Implant
// Cost: low ……….HIGH

// Donor dilemma no problem $$$

// Success rate: high high

// Best age: 8- early 20's after 18 years

// Orthodontically viable Excellent anchor unit

// Susceptible to caries Excellent hygiene-needed

// Prosthodontically complete Needs prosthesis

// Osteogenic potential No Osteogenic potential

15. advantage of
Transplantation over Implantation
Implants will not grow and result in
infraocclusion.
Hertwig epithelial root sheath allows
healing and
regeneration of the pulpal tissue saving
subsequent root canal procedure.
O steoinducing potential of the
periodontal ligament (PDL) cells-bone
regeneration between gap of the walls
of socket and the transplanted tooth.
