Laser Surgery Flashcards
Diode lasers limit tissue removal to the ___
Soft tissue.
What are some advantages of the diode laser?
Ease of use
Ability to maintain hemostatic environment
Minimal discomfort to patient with topical anesthetic
Soft tissue specificity
No requirement for sutures
What are some clinical uses with diode lasers?
Slowly erupting teeth and gingival overgrowth no longer delay treatment tcompletion
Unaesthetic gingival contours and margins, along with gingival hyperplasia, can now be managed in coordination with incisal recontouring to produce the most esthetic treatment outcome
Name 6 procedures that an orthodontist should consider using with a laser?
Gingival recontouring
Removal of hypertrophic tissue
Apthous ulcer management
Facilitation of tooth eruption
Operculum removal
Frenectomies
Gingival recontouring is indicated in patients with ____, where inflamed gingiva, pseudopockets and difficulty brushing and flossing are present
Poor hygiene
Why would an orthodontist recountor gingiva prior to bracket placement?
Excessive gingival tissue may prevent the orthodontist from placing brackets in their ideal position. The removal of this excess gingival tissue permits the orthodontist to bond a bracket to the tooth in the desired position in a timely manner
With a diode laser, the orthodontist has the ability to lase the apthous ulcer, which result in what two things?
Relieves patient of pain
Speeds up the healing of the lesion
When a diode laser is used for apthous ulcer management, the diode laser is activated for ___ seconds at a very low wattage or with a ___ tip, and kept at a distance of __-__mm away from the lesion.
30
Non-activated
1-2
Apthous ulcers generally take up to __ days to heal, but with laser treatment, the ulcers may heal within ___ after laser treatment.
1 day
True or false… many months of treatment can be saved in cases with labially placed high cuspids that are taking a long time to erupt through excessively tough gingival tissue.
True.
Unerupted teeth should be palpated, visualized, and localized by radiographic images to determine if laser uncovering is warranted
After operculum removal of second molars, how long should the orthodontist wait to place a band or bond the tooth?
They should place it immediately
With the diode laser, the light energy is absorbed by ____, which allows exceptional control of ___ at the surgical site.
Melanin pigment found within the cells
Bleeding
True or false… with the diode laser, the laser tip actually is intended to gently touch the surgical site.
True, which allows the operator to have tactile feedback during ablation
With the diode laser, the wavelength is roughly ___, which is readily absorbed by ___ and ___, and poorly absorbed by tooth structure and metal, making diode lasers ideal for soft tissue surgeries
810-980nm
Melanin
Hemoglobin
The ideal maxillary central incisor should be approximately ___ width compared to height. It is important to assess if a tooth disproportion is due to ___, ___, or ___. Depending on the cause of disproportion, what are the three treatments?
66%-80%
Short clinical crown
Gingival overgrowth
Delayed passive eruption
Waiting for eruption
Gingival recountoring
Dental restoration
What is the gingival shape of mandibular incisors and maxillary laterals?
Symmetrical half-oval/circle; therefore their gingival zenith should be located within their longitudinal axis
What is the gingival shape of maxillary centrals and canines?
Elliptical with a gingival zenith that is distal to the longitudinal axis
Most orthodontists will use the ___ to determine bracket placement height because…
Incisal edge
They find that they may be unable to place a bracket in an ideal location because of gingival overgrowth or delayed passive eruption. In these cases, it would be very helpful for the orthodontist to be able to remove any excess gingival tissue in order to place the brackets in an ideal position rather than waiting for eruption or referring the patient to a periodontist to have the teeth uncovered.
____ can sometimes cause redundant tissue to appear, especially in conjunction with poor oral hygiene. Removal of this tissue allows the patient to keep these areas under hygienic control and allows for more effective ___
Closing large extraction spaces
Space closure
When performing a gingivectomy, apply topical anesthetics and use a probe to mark height guides, leaving __ of sulcus when finished to preserve ___
1mm
The biologic width
After ideal contours are achieved in laser gingival recountoring, what should you do?
Clean the area with a micro brush or cotton roll with 3% hydrogen peroxide
What is the technique for performing a frenectomy with a laser?
First place topical anesthetic
Hold the upper lip and lightly pul the lip forward until the frenum is taut
With the laser set at 1.0 watts, lase the frenum horizontally approximately 3mm from the frenum base, and use light, continuous strokes until the lip is released from tension, leaving a V-shaped wound approximately 1cm wide
Continue to lase any deeper fibrous attachments to prevent reattahment
Then, Lansing parallel to the gingiva, smooth the remaining tissue at the base of the frenum
Clean the surgical site with 3% hydrogen peroxide on a microbrush
