between the living bone and the surface of a functionally loaded endosseous implant.
Fibrointegration: it is the presence of non-differentiated fibrous tissue that will form a
pseudoligament that will lead to implant failure
Biotolerated: when there is no fibrous tissue intervening between bone and implant
Osteoperception: mechanoreception in the absence of a functional mechanoreceptive input
periodontal and derived from the different articular, muscular, and cutaneous mechanoreceptors,
mucosal and periosteal structures that provide mechanosensory information for sensitivity
oral kinesthetic in relation to the mandibular function and the contacts of artificial teeth.
Primary stability: it is the stability that is purely mechanical, as it corresponds to the
resistance and stiffness of the bone-implant union due to the pressure of the implant at the time of its insertion,
determining whether it is possible to subject it to load or not.
ISQ is the English acronym for Implant Stability Quotient, a scale from 1 to 100 to represent
a measure of the stability of an implant. The ISQ scale has a non-linear correlation with the
micromobility. With over 1300 scientific references, we now know that high stability
an ISQ value above 70 means; between 60 and 69, it is considered medium stability, while
An ISQ value below 60 indicates low stability.

explain the classification of implant types according to healing time
Immediate: The implant is installed up to 24 hours after extraction.
Implant installed 2 to 3 weeks after extraction
Late or conventional: delayed implant. Implant installed 4-6 months after extraction.

fenestration: it is a defect after the positioning of the implant, associated with a lack of
bone thickness, which creates a partial exposure of the implant
Dehiscence is a vestibular or linguo-palatal defect, occurring after the positioning of the implant.

Saucerization: loss of marginal bone around the implants, with a more vertical pattern

Success in implants according to the Pisa consensus is:
Optimal health success
a) Without pain or sensitivity in function
b) 0 mobility
c) Radiographic bone loss of 2 mm since the surgery
d) Without a history of exudates
Successful survival
Without pain in function
b) 0 mobility
c) Radiographic bone loss of 2-4 mm
d) No history of exudates
Compromised survival
a) It may have sensitivity in the function
b) Without mobility
c) Radiographic bone loss of 4 mm (less than
1/2 of the body of the implant
d) Probe depth 7 mm
It may have a history of exudates
Failure (clinical or absolute failure)
Any of the following:
a) Pain in function
b) Mobility
c) Radiographic bone loss of 1/2 length of
implant
d) Uncontrolled exudate

Classification of peri-implant diseases, signs and symptoms. Treatment protocol
Peri-implant health: which is characterized by the absence of erythema, bleeding on probing,
inflammation and suppuration. It is not possible to define a compatible probing depth distance.
with health; at the same time, there can be health around the implant with reduced bone support.
Peri-implant mucositis is defined as an inflammatory lesion lateral to the epithelium of the pocket rich in
vascular infiltrate, plasma cells, and lymphocytes without extensive apical extension. Clinically, it presents
bleeding upon gentle probing; erythema, inflammation, and purulence may or may not be present, the
Increase in depth can be relevant data.
The treatment of peri-implant mucositis is based on the non-surgical removal of the

Guided Tissue Regeneration
Surgical application of a biocompatible membrane - resorbable or non-resorbable - to isolate
and protect the bone defect. It prevents the migration of tissues inside the defect.
Guided Bone Regeneration (GBR) is currently considered a
therapy of great importance in Implantology, to promote bone regeneration in defects
Maxillary bone; the purpose is to create a suitable bed for the positioning of implants.
Utility
Guided bone regeneration aims to increase bone volume by creating sufficient
healthy bone to place dental prostheses conventionally, or with dental implants
osteointegrated.

Types of prosthetic loads
Immediate function: the one that occurs within 48 hours following the insertion of the
implant
Early function refers to that functional load that occurs in the period that elapses during
the first two weeks after the insertion of the implants.
Delayed function: to refer to the loading functions that are applied after the first two weeks
from the placement of the implants, before completing the peri-implant bone apposition.
Types of bone grafts used in implantology
Autologous: Obtained from the same patient, it possesses osteogenic and osteoinductive properties.
osteoconductive, easy to manipulate and more biocompatible, main disadvantage morbidity in
the donor zone
Xenografts: A xenograft is a material originating from a different species than that of the recipient.
Contains only the bone mineral part (inorganic component), the organic component is removed.

Allografts: obtained from individuals of the same species, not genetically related to the.
receptor, has osteoinductive and osteoconductive capacity, behaves as a structure
which will allow bone neoformation from the gradual replacement that the graft undergoes by the
host bone.
Alloplastics: they are biocompatible grafts made from inert materials, they possess
osteoconductive properties, they are quickly reabsorbed.
