This document discusses indications and contraindications for dental implants. It lists many reasons why dental implants may be preferable to removable dentures, such as poor oral coordination, low tissue tolerance, psychological issues with removable dentures, and unfavorable tooth positioning. It also lists contraindications like acute illness, pregnancy, uncontrolled diseases, radiation therapy, bisphosphonate use, unrealistic expectations, lack of experience, inability to restore teeth or maintain oral hygiene. It describes the three main types of implants - endosseous, subperiosteal, and transosseous - and their components. It also discusses the chemical and biological properties of common implant materials.

4.  Generally any edentulous area can be
an
indication for dental implants.
 Severe morphologic compromise of
denture supporting areas that
significantly undermine denture
retention.
 Poor oral muscular coordination.
 Low tolerance of mucosal tissues.
 Para-functional habits leading to
recurrent soreness and instability of
prostheses.
 Active or hyper active gag reflexes,
elicited
by a removable prosthesis.

5.  Psychological inability to wear a
removable prosthesis even if adequate
denture retention and stability is there.
 Unfavorable number and location of
potential abutments in a residual
dentition.
 (Adjunctive location of optimally placed
osseointegrate root analogues would
allow for provision of a fixed
prosthesis.) .
 Single tooth loss to avoid
involving neighboring teeth as
abutments.

6.  Acute illness .
 Terminal illness .
 Pregnancy .
 Uncontrolled metabolic disease .
 Tumoricidal radiation including the implant site .
 History of intravenous bisphosphonate therapy .
 Unrealistic expectation .
 Improper motivation .
 Lack of operator experience .
 Unable to restore teeth prosthodontically .
 Inability of patient to manage oral hygiene.
 Patient hypersensitivity to specific components of the
implant.

2. SUBPERIOSTEAL .
3. TRANSOSSEOUS .

8.  Endosseous subdivided as follows :
– Root form.
– Blade (plate) form.
– Ramus frame.
 Subperiosteal subdivided as follows :
– Complete.
– Unilateral.
 Transosseous subdivided as follows :
– Staple.
– Single pin.
– Multiple pin

 UV light sterilization
 Gamma Radiation procedures.

40.  Dental Implantology in the 1950’s was judged to be rather
disorganized. Treatments provided were said to be often not
as successful as in other specialty procedures like
Orthopedic & Cardiovascular Surgeries.
 This discipline evolved in 1970’s. The basis for this was the
successful use of synthetic bio materials.
 Hence, the synthetic biomaterials have evolved & are now
constituted, fabricated & provided to health care
professionals as mechanically & chemically clean devices
that have high predictability of success when used
appropriately within surgical disciplines.
