Implant Position - Surgical Considerations Flashcards
What is the distance needed in mm between the implant and natural tooth?
1.5 mm
What distance is needed between implants in mm?
3 mm
What mouth region has these bone requirements? • 2mm buccal bone • 3-4mm apical to CEJ of adjacent tooth • 1.5-2mm from adjacent roots
anterior region
What mouth region has these bone requirements?
• 1mm buccal bone
• 1.5-3mm apical to CEJ of adjacent
tooth
• 3-4mm from adjacent roots
posterior
When the measurement from the dental contact
point to the crest of bone was ___________ the papilla was present 98% of the time.
5 mm or less,
When the distance was ____mm, the papilla was
present 56% of the time.
6 mm
When the distance was ___ mm or more, the
papilla was present 27% of the time or less.
7 mm
The mean height of the papillary tissue
between two adjacent implants is _______
3.4mm (2 to 4mm)
t/f: The level of interproximal papilla of the
implant is independent of the proximal bone
level next to the implant.
true
t/f: The level of interproximal papilla of the
implant is related to the interproximal bone
level next of the adjacent teeth.
true
t/f: Greater peri-implant mucosal dimensions
were noted in the presence of thick peri-
implant biotype vs thin.
true
t/f: Minimum 2mm of bone required
between the apical end of an
implant and neurovascular
structures
true
What is the minimum amount of attached (keratinized) tissue needed around an implant?
2 mm
Staging of implant surgery:
type _: IMPLANT IS PLACED IMM EDIATELY FOLLOWING TOOTH EXTRACTION
• Very difficult procedure. Requires a very skillful and experienced surgeon. • Implant is stabilized mainly in the apical region. • Mainly done when all 4 walls of extraction socket are maintained. • Great for maintaining papilla height for anterior teeth.
type I
Staging of implant surgery:
type _: IMPLANT IS PLACEDIN A SITE WHERE SOFT TISSUES HAVE HEALEDAND MUCOSA IS COVERING THE SOCKET ENTRANCE
• Similar to immediate loading, except: - Allows more soft tissue to cover extraction site and is easier to close wound. - Does not preserve as much papilla height.
type II
Staging of implant surgery:
type _:IMPLANT IS PLACED IN A SITE WHERE SUBSTANTIAL AMOUNTS OF NEW BONEHAVE FORMED IN THE SOCKET
• Allows more bone to be formed inside extraction socket giving the implant better stability. • If bone substitutes are used, needs to be of fast resorption to allow new bone formation within the 12-16 weeks.
type III
Staging of implant surgery:
type _: IMPLANT IS PLACED IN A FULLYHEALED RIDGE
• When extensive grafting is needed to compensate for missing bone. • If bone substitutes are used, needs to be of slow resorption or mixed to allow new bone formation without resorbing too quickly. • Most of the time needs at least 6 months
type IV
tissue loss Classes:
Class ___:
buccolingual loss of tissue with normal height in apico-coronal direction
class I
tissue loss Classes:
Class ___:
apico-coronal loss of tissue with normal ridge width in buccolingual direction
class II
tissue loss Classes:
Class ___:
combination of buccolingual and apico-coronal loss of tissue resulting in loss of normal height and width
class III
