ManualImplant Superstructures for Crown and Bridge Restorations passion vision innovation

Cultural historical finds indicate that humans tried to replace missing teeth by homeo- or alloplastic materials (human or animal teeth, carved bones, ivory or mother of pearl items) from very early on. What is known as dental implant today was first inserted towards the end of the nineteenth century. Today's customary implant shape was inspired by that of the natural root of the tooth and used for the first time in 1939. Since that time, implantology has been continuously further developed and has become an important element of dental restorative treatment. Dental implantology requires well-founded...

Navigation The fabrication of a functional and aesthetic implant-retained restoration involves interwoven clinical and technical procedures for which various dental products are used. This Manual describes the different procedures for the fabrication of implant-retained prosthetic restorations. The navigation shows the sequence of procedures for an implant-retained restoration in six main working steps. Each step is again divided to provide a more detailed overview of the individual processes. The red ticks within the working steps indicate the processes explained in this Manual. The colour code...

Implantology Introduction to dental implantology Implantology is the science of implanting foreign (alloplastic) materials to replace endogenous (lost) organ functions with the objective of tissue-friendly setting (biointegration). Dental implants may also be called artificial roots which are implanted into the jaw bone in the place of missing teeth. In dentistry, dental implants are alloplastic materials, which are incorporated in the area of the mucous membrane-periosteum epithelium and/or the jaw bone in order to retain dental restorations. We are working with open implants in dentistry, which...

Patient selection - healthy oral and overall situation of the patient - correct information of the patient about the treatment procedure and the intended treatment result Bone quantity - the available bone structure of the maxilla and mandible determines the indication and the selection of the implant system - in case of an atrophied alveolar process, reconstruction of bones by means of augmentation techniques Bone quality - the suitability is determined by two different bone structures (compacta, spongiosa) and is sub-divided into four categories I-IV Implant material - the requirements, such...

Surgical procedures in the implant technique are divided into: - soft tissue intervention (gingiva, mucosa) - hard tissue intervention (bone) The planned implant position of the diagnostic model is transferred to the intra-oral situation with the help of a drill template or a navigation system. Superstructures Fixed or partly removable: Individually fabricated crowns and bridges - purely implant-retained - one or several implants connected with natural abutment teeth (hybrid bridge) Removable or partly removable: - implant-retained over dentures - implant-retained hybrid dentures Occlusion -...

Implant The term implant describes the part of an implant system that is anchored in the jaw bone. The implant can also be called 'artificial tooth root'. Primary element / endostructure = "Implant" Implant apex – The implant apex is the lower (apical) part of the implant body, through which the vertical force exerted on the implant is transmitted to the jaw bone. Screw implants transmit the vertical force via the thread into the bone. Implant body – The part of a root replacement that is positioned in the bone (intra-ossal) is called the implant body. The coated, perforated implant bodies are...

Superstructures A superstructure comprises everything that is retained by the implant and protrudes into the oral cavity, i.e. secondary and tertiary elements. Secondary element / mesostructure = «Abutment» Abutment – The abutment is the part of a one- or twophase implant system which is connected to the implant or fixed to it. It is the build-up that protrudes into the oral cavity, which is either directly included into the superstructure or which serves as a connection element between the implant and the superstructure. Implant abutment screw – The implant screw, also called abutment screw,...

Planning of implant-retained prosthetic restorations The main objective of implant-retained prosthetic reconstructions is the restoration of the function. By means of augmentative procedures and membrane techniques, implants may be inserted wherever they are useful in connection with interdisciplinary treatment planning and permit good aesthetic results. Aesthetic aspects have become increasingly important in implant prosthetics. The possible treatment plan and prosthetic restoration should be defined in advance by the entire team consisting of jaw surgeon, dentist, and dental technician. A carefully...
