[QUOTE="CoolHandLuke, post: 271595, member: 4850"] except for several very large key drawbacks. 1. titanium is rigid. this means if the implant is under ANY amount of stress it will be so for its (reduced) lifespan. to be long term workable the implant needs to be passive fit. if you load unsplinted implants before osseointegration is done, you are (as we canadians say) hooped. 2. acrylic may be easily repairable and easy to put teeth in, but it breaks with far less masticatory force (edit: far less masticatory force than some other materials suitable for replacing tooth area, as opposed to gingiva or frame resins). its porous and you know why thats bad. it doesnt resist heat deformation. 3. everyone who makes these bars and dentures makes them retentive but slightly loose fitting. because they have to come off. this is why someone invented Locators. you dont want loose fitting but you want it to come off. but locators suck. suck so hard. you are replacing housings and washers every year, sometimes along with dentures themselves, if not implants. no, ti bars and acrylic dentures are in dire need of technological upgrade. its a travesty how the C and B world have advanced but denturism has not. at long last Trinia has arrived to champion the cause, however it too has its failings. failings many are working to rectify - me included. we've got our own method to correct for these issues and its a matter of ironing out the process to be easier and have more guarantees of success. all being well, 2018 we're hoping to roll out something. but not yet.
