Oral surgery Flashcards
(24 cards)
What are the suture material requirements?
Tensile strength
Stability - to maintain wound integrity
Elasticity - to adapt flaps to surface
Defined functional period - until epithelial healing
Plaque resilience
Visibility
Easy to handle
Atraumatic
What is the difference between atraumatic and traumatic needles?
Traumatic - you have to feed the thread in the needle
Atraumatic - thinner needle and already attached to the thread
What are straight needles used for?
Suturing through papillas
What are the different blade types of sutures? (image pg72)
Taperpoint
Tapercut
Spatula
Reverse cutting
Prime reverse cutting
Prime conventional cutting
Counterpoint spatula
What is the most commonly used cutting edge of a suture?
Reverse cutting - outside of curve has a pointing and cutting aspect, but inside is not cutting.
What is the more invasive suture?
Prime conventional
What are the different suture characteristics?
Resorbable vs non-resorbable
Braided vs monofilament
Suture material
What is the difference between braided and monofilament sutures?
Multiple filaments braided to a thicker/stronger material, but is more plaque retentive in comparison to monofilaments
What is the most common suture material?
Vicryl
Describe silk as a suture material in terms of origin, resorbability, structure, ease of knotting, plaque retention
Black, natural origin, not resorbable, braided, easy to knot, very plaque retentive
Describe polyester/ethyle ne terphthalate (ethibond) as a suture material in terms of origin, resorbability, structure, ease of knotting, plaque retention
Green, synthetic, not resorbable, braided uncoated or coated, not easy to knot, less plaque retentive
Describe prolene as a suture material in terms of origin, resorbability, structure, ease of knotting, plaque retention
Blue, synthetic, not resorbable, monofilic, knots loosen quickly, good plaque retention
Describe ePTFE/Gore Tex as a suture material in terms of origin, resorbability, structure, ease of knotting, plaque retention
White, synthetic, not resorbable, monofillic, very easy to knot and least plaque retention
Describe Vicryl as a suture material in terms of origin, resorbability, structure, ease of knotting, plaque retention
White, synthetic, resorbable, braided, moderately easy to knot and moderate plaque retention
What does it tell you on a suture packet about the suture?
Material
Structure
Cutting edge of the needle
Roundness and length of needle
Length of suture
Thickness
Pros and cons of resorbable sutures
Resorbable sutures mean patients do not have to come back, but do have an extended foreign body reaction, taking longer for the body to resorb it
What materials can be used for post-XLA complications?
Surgicel
Bone wax (OUTDATED)
Alveogyl
Coe-pak
What is surgicel?
An absorbable haemostat
Oxidised cellulose polymer
Foreign body
When is surgicel indicated?
Continuously bleeding sites
Patients with certain bleeding disorders/medications
Higher risk environments eg GA
What are the properties of Alvogyl/Alveogyl?
Antiseptic analgesic ingredients
Non-resorbable
Relies on it falling out or washing out, so do not heavity pack it
CAVE –> can cause foreign body reaction and extend inflammatory process
When is Alveogyl commonly used?
In patients suffering from dry socket
What is Coe-pak?
Eugenol free, surgical dressing and periodontal pack
Protection of surgical sites
CAVE –> complex handling, very sticky, might stick to sutures and make removal very difficult, hard to clean for patient (needs lots of water and vaseline to handle)
What materials can be used in apicectomy’s?
IRM - intermediate restorative material: a polymer reinforced ZOE material
MTA - mineral trioxide aggregate
