In edentulous patients –with few or no centric teeth– the Try-in is used to determine and confirm the vertical dimension and midsagittal line of maxillary and mandibular dental arches, as well as the patient’s bite.
What we need from the patient:
Impressions VPS PVS or digital, bite registration, and master casts.
Dental Cone-beam Computed Tomography (CBCT)
Pictures of the patient’s bite –center, left, and right.
What the Lab does:
Duplicate and scan the model or uses, if it is the case, digital impressions for designing and printing the pre-surgical denture.
The doctor will use the Try-In to adjust the Try-in patient’s bite, modify contours and take Photos.
It is the initial stage of CHROME guided smile surgery’s process. It is designed and fabricated from a master cast. The purpose of the Pin-supported Guide is to deliver the bone reduction guide. During the surgery, the PG is assembled to the bone reduction guide to ensure the surgery accuracy. The Pin-supported Guide will seat exactly either the patient is dentated or edentulous. It will verify tooth position.
The Bone Reduction Guide is a very important component which is placed in the second step of the CHROME surgery’s process. It is made from a metal alloy –CR/CO — which provide stability and fixation. It is attached to the bone and its main purpose is bone reduction, all hard tissue bellows the guide will be removed. Another important function is to support during the surgery three important components: Guided Implant Bed, Carrier Guide, and Rapid Appliance.
This is a key component placed on the Bone reduction guide in the third stage of the surgery. It guides and controls the trajectory, depth, and rotation of the implants. In addition, it controls the use of spoons or drills during the implant’s placement. A list of guided kit is available upon request.
The Osteotomy Guide is adapted to any implant system. In the specific Manufacturer implant system’s case, the guide comes with inserts that match with the original equipment. If the implant system is non-specific it will be a customized design.
The guided design is unique, it raises above the bone which allows the doctor full vision to place the implants. Depending on if the implant is angled or straight the shape of the guide can be hexagonal or round. The Hexagonal shape helps with the angled implants’ placement and rotation.
Once the implants are in position, the Osteotomy guide is removed, and the Carrier Guide is placed on the Bone Reduction Guide. This is the fourth stage of the surgery. It will show the position and rotation of the implants, the multiunit abutment’s screw orientation. Angled implant is identified on the Carrier Guide with marks at Osteotomy site.
The Carrier Guide has two plastic extrusions that help to deliver the prosthesis and the Rapid Appliance on the proper place, as expected.
The Rapid Appliance is a duplicate of the surgical long-term prosthetic used in the Immediate Loading process. It is picked up the day of the surgery and held until the final conversion occurs. It is very important during the final restoration process to make adjustment and collect the data needed for verifying bite, occlusion, implant position, and vertical dimension.
The adjustment is made to equilibrate and seat properly the dentures.
The provisional is the printed immediate load prosthetic that is delivered during the day of surgery. It is made for mid-term post-surgical use and provides the right information for designing the final restoration. As temporary it looks natural, it is esthetic, functional, and strong enough to last the time needed
- No T- bases to come out.
- Require only 10 mm vertical space.
- Flexible enough to eliminate chances of fractures.
- 100% Digital Processed.
- Can be reproduced in 4 hours.
- High precision fit.
The full zirconia restoration is milled out of a zirconia puck and then sintered. The result is a solid piece of zirconia, except for the pink porcelain used for aesthetics on top of the zirconia. It is a monolithic restoration incredibly durable and robust. However, a standard denture is still a great option for patients on a more limited budget.
