[QUOTE="MolarMania, post: 332522, member: 19513"] Loctite- an absolute no-no for many obvious reasons Bone interface issue causing impingement would have pretty much been solved after the first “retightening” to a specific torque. Especially if a new screw was used. The bone would have receded by then. Remember also once a thread on the screw is stretched the true characteristics of the screw/implant interface properties are changed. You do want some thread stretch, but that is defined by the manufacturer. Was it torqued to manufacturers recommendations? Is the dentist’s wrench calibrated properly or is it 18 years old? Notice the angulation of the implant and direction of the opposing arch forces. Make sure to leave out of occlusion in all excursion movements. Just hope that cheek biting won’t be an issue If you have to relieve the entire buccal cusp. Definitely do not polish the connection. Dess has some great quality products. Their products are machined to high tolerances with quality alloys. Don’t be fooled by by gaugers. Just some thoughts. Glad the new case is in and hope all goes well! [/QUOTE]
