- 88. PREMATURE BREAKDOWN OF INCISION • excessive pressure from the removable prosthesis, • supracrestal profile of the implant with cover screw in place • surgical trauma to the tissues, • poor tissue quality and • poor healing. • Poor incision design. • Poor incision & suturing. • If the alveolar crest is thin with the band of KG over the thin portion of the crest, bisecting the KG may create a difficult dissection of the flaps because the gingiva will be thin over the thin crest. • In case of traumatic dissection- Layered suturing. • Avoid re-suturing.

Editor's Notes
- Length of crown Missing papilla Broad crowns Food impaction Speech Hygiene Adjacent teeth are preserved Dental implants help to preserve the health of natural teeth as they share the occlusion load. Preserves occlusion Hygienic One additional and very important benefit can be reduction or elimination of bone shrinkage or atrophy commonly related to tooth loss Maintenance of VDO Regained proprioception Increased stability, retention and support of soft tissue Maintenance of muscles of mastication and facial expression Improved phonetics and psychological health SMILE WITH CONFIDENCE Prosthesis over implants lasts longer Replacement of teeth look, feel and function more like natural teeth . Improve taste and appetite (less coverage of the palate ) Improve cosmetic appearance. Ability to chew without pain and gum irritation . Foods that were unable to eat are back in the diet. No longer need to use the distasteful adhesives.
- Limitations in opening may affect the treatment plan in extreme conditions. The presence of undiagnosed pathologic and dental infection, as well as mucosal infections, must be treated to completion before implant placement.
- The prothrombin time (PT) and its derived measures of prothrombin ratio (PR) and international normalized ratio (INR) are measures of the extrinsic pathway of coagulation. They are used to determine the clotting tendency of blood, in the measure of warfarin dosage, liver damage, and vitamin K status. PT measures factors I, II, V, VII, and X. It is used in conjunction with the activated partial thromboplastin time (aPTT) which measures the intrinsic pathway. he reference range for prothrombin time is usually around 11–16 seconds; the normal range for the INR is 0.8–1.2. Clinicians desiring therapeutic anticoagulation may aim for a higher INR - in many cases 2.5 - using anticoagulants such as warfarin.[1 The prothrombin time can be prolonged as a result of deficiencies in vitamin K, which can be caused by warfarin, malabsorption, or lack of intestinal colonization by bacteria (such as in newborns). In addition, poor factor VII synthesis (due to liver disease) or increased consumption (in disseminated intravascular coagulation) may prolong the PT.
- The surgical placement of implants for a full-arch crown and bridge prosthesis with individual porcelain teeth requires meticulous planning and placement of implants to locate them within the confines of the crown, avoiding the embrasure spaces.

- ). The lateral cephalogram demonstrates the slopes of the cortices of the mandible and the skeletal ridge relationships of the mandible to the maxilla, and it provides a simple and inexpensive radiographic assessment of anterior height. If desired, foil can be placed over the anterior teeth in a set of dentures, which if worn during exposure of the lateral cephalogram, can demonstrate clearly the relationship of the teeth to the ridge and the ridge relationships. This provides insight as to angulation of the implants to place then in ideal locations for the implant supported or tissue supported prostheses.
- The fixed implant rehabilitation of edentulous maxillas with favorable anatomy and favorable arch position, favorable anatomy, and unfavorable arch position, and unfavorable anatomy and favorable arch position.
- If the attachment of the mentalis muscle is 3 mm or more labial to the location of the attached gingiva on the alveolar crest, a crestal incision can be If the location of the mentalis muscle is adjacent to the alveolar crest, which would result in mobile unattached gingiva directly against the implant abutment when restored, a vestibular incision is used. A type of lipswitch vestibuloplasty is performed to reposition the muscle attachments inferiorly, resulting in nonmobile tissue on the labial -surface of the implant abutment complex. Difficult dissection. lipswitch vestibuloplasty contraindicated because displacement of the mentalis musculature in an atrophic mandible will result in a drooping, &quot;witchlike&quot; chin deformity. 10-15mm Mentalis muscle attachment is must
- For the atrophic mandible with 12 to 8 mm vertical bone height, the locations of the incisions and implants and the location of the incision for second-stage surgery are critical for successful restoration. The incision for placement should be placed to avoid loss of KG. Thus the incision placed at the anterior border of the mandibular alveolar crest, typically labial to the KG, allows for an adequate dissection.
- Attempts to enlarge the band of attached ,KG do not have a high rate of success because the lip muscles tend to displace the graft from the host bed.
- CRESTAL INCISION AND DISSECTION. The crestal incision should bisect the band of KG. Bisecting the KG is important to avoid a potential soft tissue problem if the incision should open during the healing period. The incision should extend along the alveolar crest posterior to the mental foramen. When the mental forame is on top of the crest, secondary to severe bone resorption, the incision should be stopped anterior to the foramen. After the Periosteum has been flected, the mental foramen is visualized and the crestial incision can then be extended posteriorly along the lingual crest, avoiding trauma to the nerve. Occasionally, vertical release incisions can be used posteriorly. This author avoids a midline vertical release incision because of increased patient discomfort during the first 2 weeks of healing. After the incision is made through the perios‑teum to the bone, a periosteal elevator is used toreflect subperiosteal flaps both labially and lingually. A clean subperiosteal dissection is important to perform because bleeding is minimal and large lingual blood vessels can be avoided. If muscle attachments are found inserting into the crest, a scalpel is used to sever them cleanly rather than tearing them, which subsequently increases bleeding and trauma to the soft tissue. The reflection of the labial tissues can be tedious because of the firm attachment of the dense fibrous alveolar crestal tissue or if the ridge is narrow. Great care should be taken to raise an intact flap without multiple tears
