Treatment planning and restoring the single posterior dental implant Managing restorative complications Some possible restorative complications Gingival hyperplasia and gingival recession 15 Clinical case courtesy of Dr. Baldwin Marchack Gingival hyperplasia occurs when the restoration is not properly contoured. In this example, due to the ridge lap design, the restoration constantly trapped debris under the ledge, and the result was gingival hyperplasia.

Treatment planning and restoring the single posterior dental implant Managing restorative complications Some possible restorative complications Occlusal overload –Loose screws –Broken screws –Broken restorations –Broken abutments –Broken implants –Minor bone loss –Severe bone loss/Implant failure 21

Treatment planning and restoring the single posterior dental implant Managing restorative complications Some possible restorative complications Occlusal overload: Loose screws 22 Clinical case courtesy of Dr. Baldwin Marchack

Treatment planning and restoring the single posterior dental implant Managing restorative complications Some possible restorative complications Occlusal overload: Broken screws –More common with older design implants and restorations –Remember, even though it was torqued originally, it is broken now –Therefore the shank should be loose in the implant 23

Treatment planning and restoring the single posterior dental implant Managing restorative complications Some possible restorative complications Occlusal overload: Broken screws Instructions 1.Use an explorer, curette, or probe and try to engage a rough spot and move in a counter-clockwise direction. 2.Use an ultrasonic scaler with a thin tip to tease it in a counterclockwise direction. 3.Use lots of water, sharp new round bur, light touch, make a dimple, 5mm deep, off-center. 4.Now use explorer or curette in a counterclockwise direction. 5.Nobel Biocare has a “screw removal kit.” This is essentially a bur that cuts in reverse. Try it manually first; if not, run handpiece in reverse, the bur will engage the screw and it will rotate out. 24

Treatment planning and restoring the single posterior dental implant 34 Managing restorative complications Some possible restorative complications Occlusal overload: Broken abutments To avoid the breaking of an abutment it is important to consider the correct loading of the restoration when planning the treatment and position of the implant. Also consider correct articulation and occlusion. When placing the abutment on the implant in the patient’s mouth it is important: To make sure that the abutment is completely seated on the implant (take x- ray for check) The correct screw is used to fix the abutment onto the implant The appropriate torque value is applied when tightening the screw (see torque guide)
