Abstract:
Dental prostheses—whether fixed, removable, or implant-supported—frequently
precipitate complications in the oral cavity, particularly when improperly fitted or maintained.
This article synthesizes current evidence on common prosthesis-related pathologies, including
inflammatory papillary hyperplasia, epulis fissuratum, and peri-implant mucositis, and proposes
a structured, evidence-based treatment paradigm. Emphasis is placed on interdisciplinary
strategies involving precision prosthesis fabrication, optimized hygiene, biomaterial selection,
and patient education to improve outcomes and prevent recurrence.

Introduction.
Dental prosthetic rehabilitation, while fundamentally aimed at restoring oral
function, aesthetics, and masticatory efficiency, is not without its biological and biomechanical
complications. Despite advances in prosthodontic materials and techniques, prosthesis-induced
pathologies remain a significant clinical concern. Lesions such as inflammatory papillary
hyperplasia, epulis fissuratum, and peri-implant mucositis represent common adverse outcomes
that can compromise the integrity of the oral mucosa, diminish prosthesis longevity, and
substantially impair patient quality of life. These conditions typically arise from a complex
interplay of chronic mechanical irritation, microbial biofilm accumulation, and individual host
response factors, including systemic comorbidities and immune function. As such, their
incidence highlights the critical need for refined diagnostic algorithms, preventive prosthodontic
protocols, and multimodal treatment strategies that address not only the symptomatic
manifestations but also the underlying etiological mechanisms. A paradigm shift toward
personalized, evidence-based prosthetic care is essential to mitigate these risks and enhance
long-term clinical outcomes.
Purpose of the study.
The purpose of this study is to explore and enhance the clinical strategies
used in the diagnosis, prevention, and treatment of oral pathologies resulting from various types
of dental prostheses, including fixed, removable, and implant-supported restorations. Despite
significant advancements in prosthodontic materials and design, prosthesis-induced conditions—
such as inflammatory papillary hyperplasia, epulis fissuratum, and peri-implant mucositis—
remain prevalent and can negatively affect oral health, prosthesis longevity, and patient quality
of life.

Materials and methods.
This investigation was designed as a prospective, longitudinal clinical
study, incorporating both quantitative and qualitative methodologies to evaluate the prevalence,
etiopathogenesis, and clinical outcomes of prosthesis-induced oral mucosal pathologies. The
study was supplemented by a narrative synthesis of contemporary literature to contextualize
clinical findings within current prosthodontic paradigms. Ethical clearance was obtained from
the Institutional Review Board (IRB) and all procedures conformed to the ethical standards of
the 2013 revision of the Declaration of Helsinki. A total of 60 participants (n = 60; age range:
35–75 years; mean age: 54.2 ± 9.6 years; 63.3% female, 36.7% male) were recruited from the
Department of Prosthodontics and Oral Medicine, meeting strict inclusion criteria based on
clinical and prosthodontic parameters. Clinically diagnosed soft tissue alterations associated with
the use of fixed, removable, or implant-supported dental prostheses
Minimum of 6 months of prosthesis usage
Absence of systemic mucocutaneous disease (e.g., lupus erythematosus, oral lichen planus)
Patient willingness to comply with follow-up and hygiene protocol
History of recent maxillofacial surgery or radiotherapy to the craniofacial region
Use of systemic immunosuppressants, corticosteroids, or chemotherapy within the past 12
months
Presence of uncontrolled systemic conditions (e.g., uncontrolled diabetes mellitus, Sjögren's
syndrome) Each patient underwent a standardized comprehensive
intraoral and extraoral
examination
, performed by two calibrated examiners to ensure inter-rater reliability (κ > 0.85).
Clinical parameters recorded included:
Lesion location, dimension, morphology, and surface characteristics
Degree of erythema, induration, pain (measured via 10-point

Prosthesis adaptation was verified using pressure indicator paste and intraoral scanners (Trios
3Shape), and occlusal contacts were examined using shimstock and articulating foil.
Panoramic radiography was utilized for all subjects; CBCT imaging was reserved for implant-
associated complications (n = 21) to assess crestal bone resorption and prosthetic-implant
alignment. In cases with suspected Candida-associated lesions (e.g., inflammatory papillary
hyperplasia), oral swabs were collected and cultured on Sabouraud dextrose agar; identification

Histopathological examination was conducted on 12 biopsy specimens to rule out dysplastic
changes; tissues were fixed in 10% neutral buffered formalin and stained with Hematoxylin &

excised using scalpel or diode laser ablation (980 nm wavelength). Post-surgical impressions
were taken using polyvinyl siloxane materials, and new prostheses were fabricated using
CAD/CAM protocols to ensure optimal adaptation and load distribution . Data were entered into
a structured digital database and analyzed using SPSS version 27.0 (IBM Corp., Armonk, NY,
USA). Descriptive statistics (mean, SD, frequency, and proportion) were calculated. Intragroup
and intergroup comparisons of treatment outcomes (e.g., VAS scores, lesion size reduction) were
conducted using:
Paired t-tests for pre- and post-treatment evaluation , One-way ANOVA with Bonferroni post
hoc correction for multiple group comparisons ,Chi-square tests for categorical data analysis ,
Statistical significance was set at p < 0.05, and Cohen’s d effect sizes were calculated to evaluate
treatment magnitude.
Results and Discussion.
A total of 60 patients completed the study protocol, and all were
included in the final analysis. The most frequently diagnosed prosthesis-induced pathology was
inflammatory papillary hyperplasia (IPH), observed in 38.3% (n = 23) of participants, followed
by epulis fissuratum in 28.3% (n = 17), and peri-implant mucositis in 25% (n = 15). Mixed
presentations were noted in 8.4% (n = 5) of patients. Across the cohort, significant clinical
improvement was observed post-intervention. Patients undergoing non-surgical therapy showed
a mean reduction in lesion size of 43.7% ± 9.8, while the surgical group (n = 18) demonstrated a
more substantial reduction (74.2% ± 7.4,
p
< 0.001). Pain intensity, as measured by the Visual
Analogue Scale (VAS), decreased from a pre-treatment mean of 6.8 ± 1.2 to 2.3 ± 0.8 post-
treatment (
p
< 0.001). Candida albicans was isolated in 61% of cases involving IPH, supporting
the role of fungal superinfection in its pathogenesis. Patients who received concurrent antifungal
therapy showed accelerated mucosal recovery and a statistically significant reduction in lesion
recurrence at 3-month follow-up (
p
= 0.032). CBCT imaging in peri-implant mucositis cases
revealed early peri-implant crestal bone loss (<2 mm) in 40% of affected implants.
Histopathological analyses confirmed benign reactive hyperplasia in all biopsied tissues, with no
evidence of dysplasia or malignancy, although dense inflammatory infiltrates were present in
75% of samples.
The findings of this study affirm the clinical significance of prosthesis-induced oral mucosal
pathologies and highlight the complex interplay between mechanical trauma, microbial

colonization, and host immunoinflammatory responses in their development. The high
prevalence of IPH and epulis fissuratum underscores the need for periodic prosthetic evaluations
and timely prosthesis adjustment or replacement to prevent chronic tissue irritation. In alignment
with previous studies (e.g., García-Cuesta et al., 2020; Klasser & Greene, 2019), our results
confirm that poorly fitting dentures and rough prosthetic surfaces are primary etiological factors
in mucosal lesion formation. Surface topography directly influences microbial adhesion,
particularly in porous acrylic bases, necessitating consideration of low-porosity, biocompatible
materials in prosthesis design. Furthermore, CAD/CAM-fabricated prostheses were associated
with superior fit accuracy and reduced lesion incidence, consistent with findings by Turkyilmaz
et al. (2021). Patients managed with an integrated approach, combining prosthetic adjustment,
antifungal therapy, and hygiene optimization, exhibited significantly better outcomes than those
treated with monotherapy. Surgical excision proved highly effective in resolving persistent
fibrous lesions, but its success was contingent upon subsequent prosthesis redesign, supporting
the theory that recurrence is closely linked to prosthesis quality and continued trauma.
The detection of Candida spp. in a majority of IPH cases reinforces the fungal etiology in
prosthesis-related stomatitis. These findings echo those of Coco et al. (2016), who demonstrated
the synergistic role of mechanical trauma and fungal colonization in prosthetic mucosal disease.
Hence, antimicrobial adjuncts should be considered a standard component of treatment in cases
where microbiological involvement is suspected. Advanced imaging, particularly CBCT, proved
valuable in early detection of peri-implant bone changes, which may otherwise be clinically
silent. Although dysplastic transformation was not observed in our sample, the presence of
chronic inflammatory changes warrants routine biopsy of atypical or non-resolving lesions,
particularly in elderly patients and long-term denture wearers. While the findings are promising,
the study is limited by its moderate sample size and relatively short follow-up period (3 months).
Longitudinal studies with larger cohorts are necessary to evaluate recurrence rates and long-term
prosthesis tolerance. Future research should also explore the potential of antimicrobial
nanocoatings, smart prosthetic sensors, and 3D-printed bioadaptive materials in preventing
lesion formation.

Conclusion.
This study underscores the clinical importance of early detection and
comprehensive management of prosthesis-induced oral pathologies, which remain a prevalent
and often underestimated complication in dental rehabilitation. Lesions such as inflammatory
papillary hyperplasia, epulis fissuratum, and peri-implant mucositis result from a multifactorial
interplay of mechanical irritation, microbial colonization, and host-related factors. Left untreated,
these conditions can compromise both oral function and patient quality of life, potentially
leading to chronic inflammation, soft tissue hypertrophy, or early prosthetic failure.
The findings demonstrate that a multimodal therapeutic approach, incorporating prosthetic
adjustment or replacement, antimicrobial therapy, patient-specific oral hygiene protocols, and,
where necessary, surgical intervention, significantly improves clinical outcomes and reduces
recurrence rates. Moreover, the integration of advanced diagnostic modalities, including CBCT
imaging, microbiological analysis, and histopathological evaluation, plays a critical role in
guiding precise, evidence-based treatment. Future strategies should emphasize preventive
prosthodontics, including the use of biocompatible materials, digital fabrication technologies,
and personalized prosthesis design to mitigate mechanical and microbial risks. In addition, long-
term patient education and routine post-prosthetic follow-up are essential components of
sustained oral health.
In conclusion, the optimization of treatment protocols for prosthesis-related oral lesions requires
a shift toward interdisciplinary, patient-centered care, supported by continuous clinical
monitoring and technological integration. Such an approach ensures not only the resolution of
existing pathologies but also the long-term success and comfort of dental prosthetic
rehabilitation.
