FLAPS, INCISIONS, GV’S AND CROWN LENGTHENING

Which of the following are correct about a Partial Thickness Flap?

Does not allow full access to bone
Periosteum remains attached to bone
Also known as a “Split thickness flap”
All of the responses above are correct.

Correct Answer

A. All of the responses above are correct.

Explanation

A Partial Thickness Flap is a surgical technique that does not allow full access to the bone, meaning that it only partially exposes the underlying bone. In this technique, the periosteum, which is the connective tissue covering the bone, remains attached to the bone. This type of flap is also known as a "Split thickness flap." Therefore, all of the given responses about a Partial Thickness Flap are correct.

Which of the following is indicated when primary closure is necessary?

RELEASED (OR RELAXED, OR PEDICLE) FLAP
PARTIAL THICKNESS FLAP
ENVELOPE FLAP
FULL THICKNESS FLAP

Correct Answer

A. ENVELOPE FLAP

Explanation

Primary closure is necessary when there is an envelope flap. This means that the flap is completely detached from the underlying tissue and can be repositioned to cover the surgical site. Primary closure involves bringing the edges of the flap together and suturing them to promote healing and prevent infection. In contrast, with released (or relaxed, or pedicle) flap, partial thickness flap, or full thickness flap, primary closure may not be necessary as these types of flaps involve leaving a portion of the tissue attached to the surgical site.

A GINGIVECTOMY can be done to eliminate suprabony pockets, provided there is enough keratinized tissue.

True
False

Correct Answer

A. True

Explanation

A gingivectomy is a surgical procedure that involves the removal of gum tissue to eliminate pockets that have formed around the teeth. This procedure is typically performed when there is an excess of gum tissue or when the pockets are shallow and easily accessible. However, it is important to have enough keratinized tissue, which is the tough, protective layer of gum tissue, in order for the procedure to be successful. Without enough keratinized tissue, the gingivectomy may not be effective in eliminating the suprabony pockets. Therefore, the statement "A gingivectomy can be done to eliminate suprabony pockets, provided there is enough keratinized tissue" is true.

In Crown Lengthening the average width of the sulcus is?

0.5-0.8mm
0.5-1.35 mm
1.0 - 1.8mm

Correct Answer

A. 0.5-0.8mm

Explanation

Crown lengthening is a dental procedure that involves removing gum tissue and sometimes bone to expose more of the tooth's surface. The sulcus is the space between the tooth and the gum tissue. The average width of the sulcus in crown lengthening is typically between 0.5-0.8mm. This measurement is important as it helps determine the amount of tissue that needs to be removed during the procedure to achieve the desired outcome.

¢ The biologic width should only include the sulcus depth and connective tissue attachment, which would make the average biologic width 2 mm.

True
False

Correct Answer

A. False

Explanation

The sulcus depth can vary greatly. By strict definition, the biologic width should only include the epithelial attachment and connective tissue attachment, which would make the average biologic width 2 mm.

Osteoplasty is the removal of non-supporting bone. Ostectomy is the removal of supporting bone.

Both true
Both false
1st true, 2nd false.
1st false, 2nd true.

Correct Answer

A. Both true

Explanation

The explanation for the correct answer "Both true" is that osteoplasty indeed involves the removal of non-supporting bone, while ostectomy involves the removal of supporting bone. Therefore, both statements are true.

How many weeks of healing are recommended after crown lengthening?

1-2 weeks
3-4 weeks
6-8 weeks
6-12 weeks

Correct Answer

A. 6-12 weeks

Explanation

After crown lengthening, it is recommended to allow 6-12 weeks for healing. This is because crown lengthening is a surgical procedure that involves removing gum tissue and sometimes bone to expose more of the tooth's surface. This procedure is typically done to prepare the tooth for a dental crown or other restoration. The healing time allows the gum tissue to properly heal and reattach to the tooth, ensuring a successful and stable restoration. It is important to follow the dentist's instructions and maintain good oral hygiene during this healing period to promote proper healing.

Which of the following is an indication for Crown Lengthening?

Teeth that have decayed or fractured below the gingival margin.
Excessive wear of the dentition.
“Gummy Smile”
Teeth with inadequate inter-occlusal space.
All of the above are an indication for Crown Lengthening.

Correct Answer

A. All of the above are an indication for Crown Lengthening.

Explanation

Crown lengthening is a dental procedure that involves removing gum tissue and sometimes bone to expose more of the tooth's structure. This is done to address various issues related to the tooth and surrounding tissues. The given answer states that all of the options mentioned (teeth decayed or fractured below the gum line, excessive wear of the dentition, "gummy smile," and teeth with inadequate inter-occlusal space) are indications for crown lengthening. This means that any of these conditions can be a reason for a dentist to recommend crown lengthening as a treatment option.
