Effect of surface treatments on the retention of implant-supported cement-retained bridge with short abutments: An in vitro comparative evaluation

Abstract

The addition of G + B to implant abutments significantly increased the retention of cement-retained frameworks. For long-term prognosis of the prosthesis; G + B modification can be a better option as compared to G + SB.

An in vitro study to compare the influence of newer luting cements on retention of cement-retained implant-supported prosthesis

“…However, the pure tensile testing was used because it has been adopted in other studies and could allow comparison of these results with previous investigations[ 11 19 22 23 ] The abutments were used 11 times repeatedly for tensile testing; this would change the retentive values of cements. The possibility that changes occur on machined abutment surfaces after cementation and removal of that may alter subsequent retention, has been pointed out in previous studies[ 18 21 24 25 26 ] The cement space used in this study is 0.05 mm, which may have compromised the retentive properties of the resin-based luting cements, as a higher film thickness would have compromised their physical properties. …”

Uprighting a mesially tilted molar using customized titanium healing abutment of an adjacent osseointegrated implant

“…This kind of surface treatment can improve the micro retention of the resin on the metal surface of healing abutment. 12 The resulting rough axial surface of the healing abutment was coated with a layer of flowable composite resin (Filtek Z350 Flow™/3 M ESPE, shade A1) to form a resin collar (Fig 3). To attach the customized healing abutment on the implant, a release incision under local anesthesia was done using blade number 15 on the surrounding implant soft tissue to decrease its tension after inserting it.…”

“…After a period of 7 to 10 days, the healing abutment was removed from the patient's mouth and attached to an implant analog extraorally, and then a surface treatment was applied using air particle abrasion with 50 μm aluminum oxide particles under 2‐bar pressure. This kind of surface treatment can improve the micro retention of the resin on the metal surface of healing abutment 12 . The resulting rough axial surface of the healing abutment was coated with a layer of flowable composite resin (Filtek Z350 Flow™/3 M ESPE, shade A1) to form a resin collar (Fig 3).…”
