MDL ® Chairside Denture Retentive Pickup Procedure
Overdenture Stabilization
For chairside pickup of the MDL ® denture retentive component transfer the position of the O-Balls to the
tissue-bearing surface of the denture by marking the heads of the O-Balls with a soft lead pencil (Fig. 1)
or capturing their impression by inserting a strip of soft silicone or soft wax inside the denture. An impression
is clearly visible on the tissue-bearing surface of the denture (Fig. 2).
Using a resin bur, relieve the opening around the abutment impressions or markings in the denture
(Fig. 3 & 4).
Try the denture in the patient’s mouth and verify that the appliance is seated passively while in maximum
intercuspation. The O-Balls should not touch any part of the denture. Have the patient close into maximum
intercuspation and observe that the denture is stable and properly equilibrated at this point (Fig. 5).
Snap a Retentive Housing Assembly over each O-Ball (Fig. 6 & 7). Try the denture in the patient’s mouth
again and check to ensure that the appliance is seated passively while in maximum intercuspation (Fig. 8).
Remove the Retentive Housings. Punch holes in a rubber dam at each implant site (Fig. 9).
