Implant prosthodontics requires a different approach than prosthodontics on natural teeth. Different input data, different materials, different requirements. Learn the key issues.
An error in implant prosthodontics is costly – both biologically and financially. Precise communication between the dental office and the lab is the foundation for success.
Accurate mapping of implant position is the foundation of good implant prosthetics. How to correctly scan a scanbody?
Two philosophies of prosthetic retention on implants – each with its own advantages and compromises.
An abutment is the bridge between an implant and a crown. Standard is faster, individual – more precise. When to choose which?
The choice of impression technique depends on implant geometry, patient anatomy, and the number of implants in one arch. There is no single answer for all cases — but there is a logic to the choice.
A standard abutment costs less. A custom abutment provides control over geometry that a standard one cannot. The question is not `which is cheaper` — but where does that difference have clinical significance.
A gingival mask is a thin layer of pink silicone applied around the dies on a working model. Its purpose is to replicate the position and shape of the gingiva at the tooth's cervical margin. Without it, the technician works without visibility of the cervical relationship – unaware of how the restoration will interact with soft tissue.
The decision between screw-retained and cement-retained restorations depends on patient anatomy, the aesthetic zone, and the treatment plan – not on habit. Below, we've compiled data from laboratory practice to help you make an informed decision.
An implant in a non-standard position isn't the end of the world. We have tools. The question is: how significant is the deviation and at what stage did you detect it?
Each abutment change after implant exposure disrupts soft tissue remodeling. OAOT (One Abutment One Time) eliminates this problem by limiting abutment changes to just one — from implant uncovering to the final prosthetic restoration.
Soft tissue is not a static frame for a prosthetic restoration. It reacts to what we place around it — it can recede, proliferate, shape, or inflame. A provisional restoration is the only tool that allows this tissue to be prepared before the definitive restoration is placed.
All-on-4 is a multi-stage protocol — not because the lab requires it, but because tissue and bone need time. Below, we describe the logic of the timeline from the perspective of a laboratory that fabricates both provisional and definitive bridges.
Tightening an implant screw "by feel" is a clinical error. Both undertightening and overtightening have consequences – loosening or fracture of the screw. Below, we've compiled parameters and procedures from daily clinical and laboratory practice.
A bridge connecting an implant to a natural tooth is one of the more challenging prosthetic cases. The biomechanical difference between osseointegration and the periodontal ligament is vast – and must be taken into account in both the occlusal design and the decision to construct such a bridge.
An implant crown is not the same as a crown on a natural tooth. The lack of cementing agent, different soft tissue biology, and different subgingival contour all influence the morphology of the restoration that the laboratory must design. Incorrect morphology leads to soft tissue inflammation, which the clinician will notice relatively quickly in clinical practice.
Overdentures are a partial solution—neither fixed implant prostheses nor conventional removable dentures. Patients must understand that this type of prosthesis requires systematic maintenance and component replacement. The laboratory must be prepared to perform this service promptly, without delays.
A printed model may look perfect—and still have implant position errors exceeding fit tolerance. A verification index eliminates this problem before milling begins. This prevention costs less than a prosthesis remake.
Multi-unit abutments are specialized connections for edentulous cases with multiple implants. They are more expensive than standard solutions, but in some cases, they are the only viable option—especially when patient anatomy does not allow for a typical bar or overdenture.
