Implants Definitions

Dental implant: It is an integral component of the oral implant complex which also consists of supportive bone, interposed keratinized & mucosal oral soft tissues & prosthetic supra structure

Osseointegration: It is defined as the direct structural and functional connection between ordered, living bone and the surface of a load-bearing implant without intervening soft tissues.

    • Trans steal
  • Based on shape
    • Blade type
    • Root form
  • Based on the material used:
    • Metallic
    • Ceramic
  • Based on surface characteristics:
    • Titanium sprayed coating
    • Sandblasting
    • Laser-induced surface roughening
    • Hydroxyapatite coating

2. Indications of implants

  • Edentulous patients
  • Partially venous

Implant Short Question And Answers

Question 1. Complications of implants.
Answer:

Complications of Implant:

  • Bemoriage
  • Nerve injury
  • Fracture of jew
  • Sematome
  • Infection
  • Mobility of implant
  • Periimplantitis
  • Edema
  • Sinusitis

Question 2. Osseointegration
Answer:

Definition of Osseointegration:

It is defined as the direct structural and functional connection between ordered, living bone and the surface of a load-bearing implant without intervening soft tissues

  • It is a fundamental requirement and essential component for implant success

Process of Osseointegration:

Implants Process Of Osseointegration

Requirements of Osseointegration:

  • Immobility of implant relative to the bone
  • Avoid excessive accusal forces
  • Proper vascular supply and oxygen tension
  • A strict aseptic technique should be maintained
  • Profuse irrigation during drilling

Significance of Osseointegration:

  • Once osseointegration is achieved, implants can resist and function under accusal forces for many years

Question 3. Reimplantation.
Answer:

Reimplantation

It is the intentional removal of the tooth and its reinsertion into the socket after retrograde obturation and resection of the root tip.

Indications of Reimplantation:

  • Broken instruments in canals
  • Calcified canals
  • Over filling
  • Curved canals
  • Presence of foreign body in periapical tissue.

Contraindications of Reimplantation:

  • Medically compromised
  • Periodontal involvement
  • Missing buccal/lingual plate
  •  Nonrestorable tooth

Technique of Reimplantation:

Implants Process Viva Voce

  1. An endosteal implant is an implant inserted in the bone
  2. Endosteal implants can be either root form or plate form
  3. The transfer coping in an implant is used to position an analog in the impression
  4. In the case of an endosseous implant, a per mucosal seal of the soft tissue at the implant surface is essential
  5. The most common type of implant in use today is endosteal implants
  6. The minimum space between implant should be 3 mm
