Why is Posterior Immediate Provisional (IP) Needed
As well known, a lot of patients are excited to know presence of immediate implants when their teeth are nonsalvageable. A few of them ask why not to place crowns immediately. When they learn the concept of micromovement, their reply is universal: "I am not going to chew with them". In fact, they apparently keep the promise. So far all of posterior immediate provisionals have succeeded. The most basic factor is that there is no occlusal contact in addition to primary stability.
In fact posterior immediate provisionals are essential in partial edentulous re-habitation. The neighboring teeth (particularly distal ones) may shift to the implant recipient area when patients have periodontal issue, bruxism and malocclusion. The immediate provisionals with normal proximal contact can prevent the restorative disaster. Provisionals can be single or multiple units. As a matter of fact, multiple units in splint appear to offer better stability.
