Fabrication of a reverse-engineered custom scan body as a digital solution for recording implant position: A dental technique.

A technique for the reverse engineering of the implant-abutment connection to fabricate a custom scan body is described. The implant-abutment connection was designed using the exocad software program, the scan body with screw channel was designed with the Blender software program, and the file was either 3-dimensionally printed in definitive tooth-colored resin with ceramic filler material or milled in polyetheretherketone (PEEK). This technique offers an accurate, cost-effective digital solution for implant optical scanning that can replace prefabricated scan bodies that may not be available for all implants.

Digital design and manufacture of a stackable implant surgical guide for immediate loading in completely edentulous full-arch cases: a dental technique.

The design and manufacture of a stackable surgical guide for implant placement with immediate prosthetic loading of completely edentulous cases is described in this dental technique. To achieve this, the stackable attachment is designed using free-form designing software, which is later joined to the implant placement guide and the dental prosthesis. This technique should provide the patient with a same-day implant and an esthetic restoration accurately placed in the predesigned position of the centric occluding relationship.

Fully digital workflow for reinforced mandibular implant overdenture - A novel method.

Mandibular overdenture is suspected to fracture, especially in the midline and anterior region due to low surface area of coverage and minimum acrylic thickness in addition to attachments pickup holes that weakens the denture. Dentures used to be conventionally reinforced with metal meshwork which cannot be done in a digital workflow. This in vitro report introduces a novel approach of digital overdenture reinforcement using computer-aided design, computer-aided manufacturing, and rapid prototyping technologies.

Digital Designing of a 3D-Printed Stackable Ear Mold for Auricular Rehabilitation: A Technical Note.

A technique for the virtual design of a three-piece stackable auricular mold for unilateral auricular defect rehabilitation using an open-source software program is described. An optical intraoral scanner is used to scan the patient's ear on both the affected and unaffected side. To maintain the relationship between the mold parts, a stackable attachment is designed and joined to the mold.

Digital fabrication of polyetheretherketone retentive bar attachment inserts as overdenture maintenance: A dental technique.

A technique for the virtual designing of retentive attachment inserts for bar-retained 2-implant mandibular overdentures is described. The bar attachment is scanned intraorally, the retentive insert designed with the MESHMIXER software program, and the file 3D printed in resin, which is replicated in polyetheretherketone (PEEK). The technique offers high-quality inserts with good retention that can replace the conventional nylon inserts and reduce the number of maintenance visits and the frequency of changing the bar attachment.
