Intended Use

Straumann® Dental implants are indicated for oral endosteal implantation in the upper and lower jaw arches for the functional and aesthetic oral rehabilitation of edentulous and partially dentate patients. Straumann® Dental implants are also indicated for immediate or early implantation following extraction or loss of natural teeth. Implants can be placed with immediate function on single-tooth and/or multiple tooth applications when good primary stability is achieved and with appropriate occlusal loading to restore chewing function. The prosthetic restorations used are single crowns, bridges and partial or full dentures, which are connected to the implants through the corresponding components (abutments). In cases of fully edentulous patients, 4 or more implants must be used in immediately loaded cases.

Device Story

Endosseous dental implants; root-form design; used for oral rehabilitation of edentulous/partially dentate patients. Implants surgically placed in jaw arches; support prosthetic restorations (crowns, bridges, dentures) via abutments. Enables immediate/early loading post-extraction if primary stability achieved. Used in clinical settings by dental professionals. Labeling change only; physical device identical to predicates. Clinical data supports use in patients with pharmacologically controlled metabolic bone disease and use of small diameter (Ø3.3 mm) implants in molar regions, moving previous contraindications/restrictions to precautions.

Clinical Evidence

Non-interventional post-market study of Roxolid Ø3.3 mm implants in molar regions (n=not specified). Primary endpoints: success/survival rates at 1 year. Secondary: bone level changes, success/survival at 2-3 years, clinician satisfaction. Results: 2-year follow-up showed minimal failures (2 in molar region) and adverse events (inflammation, resorption) which resolved. Literature review supported safety in patients with controlled metabolic bone disease. Evidence supports equivalence to implants placed in other mouth regions.

Technological Characteristics

Endosseous root-form dental implants. Materials, surface treatments (SLA, SLActive), and design are identical to predicate devices. No changes to energy source, dimensions, or sterilization. Standalone mechanical devices; no software or electronic components.

Indications for Use

Indicated for edentulous and partially dentate patients requiring oral endosteal implantation in upper/lower jaw arches for functional/aesthetic rehabilitation. Suitable for immediate/early implantation post-extraction/tooth loss. Supports single-tooth or multiple-tooth applications with immediate function if primary stability is achieved. Requires 4+ implants for fully edentulous immediate loading.

Regulatory Classification

Identification

## Device Description:

This premarket notification serves to affect a labeling change applicable to all endosseous dental implants of the Straumann® Dental. Implant System. The subject devices are physically identical to the listed predicate device descriptions are identical to those presented in the referenced predicate submissions.

The proposed Straumann Implant Instructions for Use (IFU) changes in this premarket notification are to address the following:

- Update the IFU content to reflect the FDA Guidance on Medical Device Patient . Labeling regarding contraindications, general warnings, and precautions
- Clarify the term "poor bone metabolism" under contraindications and move the . condition "osteoporosis" to Precautions in the IFU
- Modify the indications for use statement previously cleared in premarket notifications . K081419 and K083550 to relocate the statement regarding specific indications for small diameter (Ø3.3 mm) implants from the indications for use to the Precautions

#### Intended Use / Indications For Use:

Straumann® Dental implants are indicated for oral endosteal implantation in the upper and lower jaw arches for the functional and aesthetic oral rehabilitation of edentulous and partially dentate patients. Straumann® Dental implants are also indicated for immediate or early implantation following extraction or loss of natural teeth. Implants can be placed with immediate function on single-tooth and/or multiple tooth applications when good primary stability is achieved and with appropriate occlusal loading to restore chewing function. The prosthetic restorations used are single crowns, bridges and partial or full dentures, which are connected to the implants through the corresponding components (abutments). In cases of fully edentulous patients, 4 or more implants must be used in immediately loaded cases.

#### Technological Characteristics:

There are no changes to the materials, surface treatments, design, fundamental operating principles, or sterilization procedures as a result of the proposed IFU changes. No new surgical instruments or secondary components are being introduced as a result of the proposed IFU changes.

#### Performance Testing:

The bench and animal performance testing previously submitted in support of the referenced predicate devices continues to be representative of the subject devices. A non-interventional clinical study was conducted in accordance with applicable national and local regulations and is being submitted as supporting documentation for the proposed IFU changes.

A review and summarization of the clinical literature associated with the use of dental implants in the presence of metabolic bone diseases was presented. The available data indicate that metabolic disease of the bone is not a strict contraindication for the use of dental implants; the evidence supports that performance of dental implants in patients whose metabolic bone disease is pharmacologically under control is equivalent to those in patients free of metabolic bone disease. This supports the relocation of the statement regarding metabolic bone disease from the Contraindications section of the Instructions For Use to the Precautions section to allow the clinician to determine whether a particular patient is a suitable candidate for dental implants.

{2}------------------------------------------------

A subset of data from a Non-Interventional Study (i.e. post-market) in humans was presented. The study as a whole included subjects with the need of dental implant therapy and restoration according to the cleared indications for the Roxolid Ø3.3 mm implant within Germany, United Kingdom, France, Spain, Sweden, the United States, and Canada. The data subset was specific to patients having implants placed in the molar region of the mouth.

The primary study purpose was to determine implant success and survival rates one year after implant placement. Secondary purposes included assessing the change in bone level (to be estimated by the investigator), success and survival rates 2 and 3 years after implant placement and assessment of other treatment characteristics including protocol, implant position, augmentation procedures and clinician satisfaction.

As of the 2-year time point, there were two reports of implant failyre in the molar region (one prior to restoration and one prior to the 1-year time point after final restoration - Table 16). There was no implant failure reported following the 1-year follow-up visit in the molar region. Other reported implant related adverse events in the molar region include two cases of inflammation (one at implant placement and one at 2-years), one case of poor implant stability (at implant placement), and one case of peri-implant resorption (at final restoration). All adverse events are known to have resolved with the exception of the report of inflammation at 2-years.

This clinical data suggest that performance of Roxolid Ø3.3 mm implants placed in the molar region is equivalent to those placed in other parts of the mouth. This supports the relocation of the recommendation against using Ø3.3 mm (small diameter) implants in the molar region from the Specific Indications section of the Instructions For Use to the Precautions section to allow the clinician to determine whether application in the molar region is appropriate for the particular patient.

#### Conclusion:

The subject devices are identical in all respects to the predicate devices identified. This submission only introduces changes to the product labeling. The data and documentation submitted in this premarket notification supports the proposed changes to the Instructions for Use for the Straumann Dental Implant System.
