2. Scientific Background

Managing patients with severe maxillary atrophy and complete edentulism remains one of the most demanding challenges in implant dentistry and oral rehabilitation. Advanced bone resorption often limits the use of conventional endosseous implants and complicates treatment planning. As digital technologies continue to evolve, renewed interest has emerged in customized subperiosteal implants, which can now be designed to match each patient’s anatomical characteristics through computer-assisted planning and modern manufacturing techniques.

This study explores this contemporary approach by presenting clinical cases in which individualized subperiosteal implants were used to rehabilitate patients with advanced maxillary bone deficiency. The work highlights the integration of digital implant planning and patient-specific implant design, illustrating how personalized solutions may expand therapeutic possibilities in complex implant rehabilitation.

3. Study Objective

The purpose of this study was to describe the clinical rehabilitation of patients with severe maxillary atrophy using custom-made sintered subperiosteal implants. The authors aimed to demonstrate the application of computer-assisted anatomical planning and individualized implant design in the management of challenging edentulous cases.

4. Methodology

This publication is a case series.

The authors report the treatment of three patients diagnosed with severe maxillary atrophy. Preoperative and postoperative radiographic examinations were used alongside computer-assisted anatomical analysis to design patient-specific subperiosteal implants manufactured through a sintering process.

The abstract does not specify the total number of implants placed, follow-up duration, detailed surgical protocol, outcome assessment criteria, or manufacturing parameters. These aspects cannot be further interpreted based on the information provided.

5. Main Findings

The three reported cases demonstrated successful rehabilitation using customized subperiosteal implants designed specifically for each patient’s anatomical condition. According to the authors, the digital planning workflow enabled accurate implant adaptation, supporting treatment in anatomically demanding situations.

The study also reports favorable characteristics regarding the biocompatibility and durability of the customized implants. No postoperative complications were observed in the presented cases, and both procedural success and patient-reported outcomes were described as highly satisfactory.

The authors emphasize, however, that continued clinical follow-up is essential to determine the long-term performance and durability of this rehabilitation strategy. No quantitative outcome measures or survival data are provided in the available abstract.

6. Clinical Analysis

This case series illustrates the potential role of customized subperiosteal implants as a personalized treatment option for patients presenting with severe maxillary atrophy. Rather than relying on a standardized implant design, the described approach utilizes computer-assisted planning to develop implants tailored to each patient’s individual anatomy, reflecting the growing integration of digital workflows into implant dentistry.

The absence of reported postoperative complications and the positive clinical outcomes observed in these three patients suggest that individualized implant design may offer a feasible solution in selected complex rehabilitation cases. Nevertheless, these findings should be interpreted cautiously.

As a case series involving only three patients, the study provides descriptive clinical observations rather than definitive evidence of treatment effectiveness. The lack of comparative data, long-term follow-up, and detailed outcome measures limits the ability to determine how this approach performs relative to alternative rehabilitation strategies. Consequently, the publication should be viewed as an exploratory contribution supporting the feasibility of customized subperiosteal implant rehabilitation rather than as conclusive clinical evidence.

7. Clinical Applications

Based on the available data, this technique may be relevant for:

• rehabilitation of patients with severe maxillary atrophy;
• management of completely edentulous patients with advanced bone deficiency;
• digital treatment planning using patient-specific anatomical analysis;
• customized subperiosteal implant rehabilitation supported by CAD-based workflows;
• personalized implant solutions for anatomically complex cases.

The abstract does not provide evidence supporting superiority over other implant rehabilitation techniques or reconstructive procedures.

8. Level of Evidence, Limitations, and Transparency

This publication represents a case series, corresponding to a low level of clinical evidence.

The findings are based on only three patients without a control group or comparison with alternative treatment modalities. Furthermore, the abstract does not report follow-up duration, implant survival rates, standardized clinical outcome measures, or long-term performance.

These methodological limitations should be considered when interpreting the reported outcomes.

No conflicts of interest or financial relationships are mentioned in the information provided.

9. Key Study Points

• Study design: Case series
• Level of evidence: Low
• Study population: Three patients
• Number of implants: Not specified in the available information
• Follow-up duration: Not specified in the available information
• Primary outcome evaluated: Rehabilitation using customized subperiosteal implants for severe maxillary atrophy
• Main finding: Successful rehabilitation with no reported postoperative complications in the presented cases
• Scientific conclusion: Customized subperiosteal implants appear to be a promising individualized rehabilitation approach, although long-term evaluation remains necessary.
• Main limitations: Small sample size, absence of control group, lack of long-term outcome data, and limited methodological details.

10. Scientific Impact

This study contributes to the renewed clinical interest in customized subperiosteal implants within modern digital implant dentistry. Rather than introducing definitive clinical evidence, it demonstrates the practical application of computer-assisted planning and patient-specific implant manufacturing in highly challenging maxillary rehabilitation cases.

Its scientific value lies primarily in documenting the feasibility of a personalized treatment strategy for severe bone atrophy. The reported cases support further investigation into digitally designed subperiosteal implants while emphasizing the importance of individualized anatomical planning.

Given the limited level of evidence, these findings should be considered preliminary. Larger prospective clinical studies with standardized outcome measures and extended follow-up will be necessary to establish the long-term predictability, safety, and clinical performance of this rehabilitation approach.

11. Editorial Conclusion

This case series presents an individualized digital approach for rehabilitating patients with severe maxillary atrophy using customized subperiosteal implants. The reported clinical outcomes are encouraging and demonstrate the technical feasibility of combining computer-assisted planning with patient-specific implant design. However, because the evidence is derived from only three clinical cases and lacks detailed long-term data, the findings should be interpreted cautiously. Further well-designed clinical investigations are required before broader conclusions regarding routine clinical application can be drawn.
