This document describes a case of a patient with microstomia (reduced oral aperture) due to extensive post-surgical facial scarring. Standard impression techniques could not be used due to the small mouth opening. The dentists innovatively used impression compound on an articulator bite fork to create a preliminary impression, allowing for complete denture construction. The patient was ultimately satisfied with the functional and aesthetic outcome, though she continues to experience recurring skin cancers. The technique of using a bite fork with compound is recommended for similar microstomia cases where small stock trays do not fit.

Pre-prosthetic surgery is that part of oral and maxillofacial surgery which restores oral function and facial form. This is concerned with surgical modification of the alveolar process and its surrounding structures to enable the fabrication of a well-fitting, comfortable, and esthetic dental prosthesis. The ultimate goal of pre-prosthetic surgery is to prepare a mouth to receive a dental prosthesis by redesigning and smoothening bony edges.

Fabrication of functional complete dentures for edentulous patients who have undergone hemimandibulectomy is a very arduous and demanding endeavor.
The most challenging situation encountered during this procedure is the deviation of the mandible to the resected side. The deviation of the mandible to the resected side is directly proportional to the loss of tissues in the area hemi-mandibulectomy has been performed.
In cases with Cantor and Curtis classes II, III, IV, and V, guide flange prosthesis would be a treatment modality. For guide flange prosthesis to be effective, the sufficient number of posterior teeth that are periodontally sound should be present in the opposite arch.
In patients where reconstruction is not done after resection of the mandible, scar tissue formation occurs over a period of time that stiffens the tissues and worsens prosthetic rehabilitation, leading to compromised treatment planning.
Multidisciplinary Approach in the Rehabilitation of Congenitally Maxillary C...Abu-Hussein Muhamad
Objective: This case report describes the multidisciplinary
approach to treat a congenitally missed maxillary canine, how to
improve patient’s smile using orthodontic fixed appliance, endosseous
dental implant, and porcelain veneer to achieve the treatment results of
function and esthetic.
Materials and procedures: Unilateral agenesis of the permanent
maxillary canines in healthy individuals is extremely rare. This
paper presents the case of a female patient diagnosed with congenital
unilateral agenesis of the permanent maxillary canines as well as
occlusal abnormalities in the form of left-side crossbite. To restore the
proper aesthetics and function, interdisciplinary therapeutic treatment
was implemented. In the case presented in this paper, the aim of
oral rehabilitation was to restore a functional balance by obtaining
proper skeletal relationships, creating optimal occlusal conditions and
obtaining arch continuity.
Conclusion: Interdisciplinary treatment combined of orthodontics,
implant surgery, and prosthodontics was useful to treat a nonsyndromic
oligodontia patient. Especially, with the new strategy, implantanchored
orthodontics, which can facilitate the treatmentand make it
more simply with greater predictability.
Partial or complete edentulism has multiple implications in relation to function, esthetics and future rehabilitative treatment. This case report illustrates the management of a patient with extreme consequences of partial edentulism in the maxillary arch and total edentulism in the mandibular arch. The main clinical findings were unopposed remaining teeth, over eruption of the remaining teeth, loss of vertical dimension of occlusion, and significant disfigurement of the occlusal plane. Following the diagnostic procedure, a well-coordinated prosthodontic treatment involving liaison with other dental disciplines was indicated. The management involved an innovative combination of fixed and removable prostheses in conjunction with intentional root canal therapy of the remaining natural teeth. Series of provisional prostheses were applied to facilitate the transition to the final treatment.
Key-words: Edentulism, Vertical dimension, Provisional Restoration, Fixed and Removable prosthesis
Prosthodontic-Orthodontic Treatment Plan with Two-Unit Cantilevered Resin-Bon...Abu-Hussein Muhamad
Abstract: Congenitally missing lateral incisors create an esthetic problem with specific orthodontic and prosthetic considerations. Selecting the appropriate treatment option depends on many factors, such us the malocclusion, the anterior relationship, specific space requirements, bone volume, root proximity, the condition of the adjacent teeth, and esthetic prediction mainly when the canine must be reshaped.Resin bonded bridges were considered to be doomed owing to their very high decementation rate, have come alive once again because of newer resin based cements. This article will discuss the variety of treatment managements in case of space opening and treated with two 2-unit cantilevered resin-bonded fixed partial dentures supported by the cuspids. This conservative treatment plan was cost-effective without having any significant biological cost. Keywords: Agenesis, Resin- bonded fixed partial denture, interim prosthesis.

Abstract: Severe atrophy of the inferior alveolar process and underlying basal bone often results in problems with a lower denture. These problems include insufficient retention of the lower denture, intolerance to loading by the mucosa, pain, difficulties with eating and speech, loss of soft-tissue support, and altered facial appearance. These problems are a challenge for the prosthodontist and surgeon. In this case report, patient with resorbed edentulous mandible was successfully rehabilitated using two dental implants placed in the interforaminal region with ball abutments opposing conventional maxillary complete denture. Key Words: dental implants; dental prosthesis, implant-supported; resorption,
Modern Treatment for Congenitally Missing Teeth : A Multidisciplinary Appro...Abu-Hussein Muhamad
The maxillary lateral incisor is the second most common congenitally absent tooth. There are several treatment options for replacing the missing maxillary lateral incisor, including canine substitution, tooth-supported restoration, or single-tooth implant. Dental implants are an appropriate treatment option for replacing missing maxillary lateral incisor teeth in adolescents when their dental and skeletal development is complete. This case report presents the treatment of a patient with congenitally missing maxillary lateral incisors using dental implants. Finally, the importance of interdisciplinary team treatment planning is emphasized as a requirement for achieving optimal final esthetics
Gingival prosthesis: an efficient solution to severe gingival recessions in a...Premier Publishers
Clinical attachment loss in periodontal disease may lead to gingival recessions, elongation of the crowns, black triangles and unaesthetic appearance of maxillary anterior. For these problems surgical procedures may not have acceptable results in case of severe gingival recessions. Thus, non-surgical methods, like gingival prostheses/veneers, should be considered as an alternative treatment approach in such cases. It is an easy constructed and practical device to optimize the esthetic and functional outcome after the control of periodontal disease. This case report of young female patient illustrates treatment for an advanced tissue loss in a maxillary anterior area using a removable gingival prosthesis/veneers. This treatment modality offered a good optional solution and optimum esthetic patient satisfaction with a 2-year follow-up.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Technique Tips: The Use of a Novel Primary
Impression Technique in a Patient with Microstomia
The prevalence of edentulous patients has
decreased in Western society. The Adult
Dental Health Survey determined that the
level of edentulism reduced from 13% to 6%
between 1998 and 2009.1
There appears to
be a changing pattern in oral health status
as patients are retaining their natural teeth
for longer, meaning that dentists are no
longer making the same number of complete
dentures as our predecessors, and may be
becoming deskilled. Therefore, when faced
with complex patients requiring complete
denture construction, dentists may feel out of
their comfort zone and in need of improved
knowledge and skills.
Microstomia describes a
reduction of oral aperture,2
which may
be congenital or acquired. It may be a
consequence of conditions including
post-surgical and radiotherapy, trismus,
cleft lip and palate, trauma, scleroderma,
temporomandibular joint disorder, Plummer-
Vinson’s syndrome, oral submucous
fibrosis or damage to the muscles of
mastication.3
Microstomia makes all
dental treatment more difficult, especially
during prosthodontic impression taking,
and prosthesis construction may even be
rendered impossible. Alternative techniques
include modifications to small stock trays by
sectioning, or using children’s stock trays.4
This report describes the
prosthetic management of a patient suffering
from extensive post-surgical circumoral
stenosis and acquired microstomia which
rendered denture construction extremely
challenging. An innovative strategy was
required for recording primary impressions,
when the smallest stock trays available
were too large to fit intra-orally. Impression
compound was adapted to an articulator bite
fork to record a primary upper impression.
Case report
A 75-year-old female attended as
a new patient requesting upper and lower
complete dentures. Her expectations of
treatment were the restoration of function
and aesthetics and reduction of saliva
drooling.
The patient had an initial
diagnosis of a basal cell carcinoma (BCC) at
the inner canthus of her right eye 22 years
previously. This was surgically removed,
eliminating her tear duct. Over the next 20
years she experienced not only a recurrence
of the original BCC, but also a further 11
BCCs affecting both right and left temples,
lips, neck, back and legs. On each occasion
she underwent surgery to remove the BCC.
In November 2014, she was diagnosed with
11 BCCs simultaneously, and underwent 7
months of chemotherapy. In August 2015,
she underwent further facial surgery. She
is a life-long non-smoker, rarely drinks
alcohol and had no other relevant medical
history or history of excessive sun exposure
to account for the numerous BCCs. After
further consideration of the patient’s
unexplained multiple BCCs, perhaps this is a
case of Gorlin-Goltz syndrome. Gorlin-Goltz
syndrome is also known as Nevoid Basal Cell
Carcinoma syndrome and comprises a rare
genetic predisposition to BCCs.5
The patient had been edentulous
for several decades, with a history of wearing
complete dentures. However, she was unable
to wear dentures since her initial surgery
in 2014 as her microstomia meant she was
unable to insert them.
On examination, extra-orally,
she had post-surgical oral stenosis, deficient
nasal septum and incompetent lips (Figure 1).
Intra-orally she was edentulous with acquired
microstomia. The maximum vertical mouth
opening was measured to be 22 mm (Figure
2), compared to the average maximum
mouth opening of 41 mm for females.4
Figure
3 shows the patient’s atrophic lower alveolar
ridge and labial sulcus.
On attempting to record primary
impressions, even the smallest stock tray
available was too large for her mouth.
Impression compound was subsequently
adapted around the bite fork of an articulator
and was successfully used to record a
preliminary impression. Functional extension
of the compound was defined in the sulci by
gentle border moulding as the soft tissues
were very tender. Border moulding was
challenging due to severe fibrosis. Impression
compound was preferable to alginate due to
improved control of flow and ability to make
minor adjustments. The impression consisted
of multiple placement of compound with
selective warming to pick up detail and
correct errors. The metal bite fork held heat
and consequently the compound remained
fluid (malleable) for longer. It needed to
be in the mouth for longer to cool and
become firm. Also the fork provided a base
but no lateral support, so border moulding
was more complex than with a stock tray.
In terms of inserting the bite fork into the
patient’s mouth, one arm was placed in,
then the other was rotated in to try to avoid
lip contact that would cause a distortion in
the compound. Figure 4 shows the primary
casts that were constructed from the primary
impressions.
The laboratory subsequently
constructed upper and lower close-fitting
special trays and major impressions were
recorded using greenstick compound
and zinc oxide eugenol. The remainder of
treatment followed the usual stages and the
patient was fitted with dentures.
Given the patient’s post-surgical
stenosis, atrophic maxilla and atrophic
labial sulcus, a Class III incisor relationship
was deemed most appropriate. At try-in,

TechniqueTips
the upper centre-line matched the midline
of her nasal philtrum. Given the patient’s
asymmetrical face, it was felt to be more
appropriate to adjust the centre-line to
match the LL1−LL2, rather than LL1−LR1, in
order to improve the overall aesthetics of
the dentures. At the next try-in, the patient
expressed high approval with both the fit
and aesthetics of these dentures, so the
fitting proceeded. After the fit stage, the
patient remained very pleased, vocalizing
that the dentures had greatly improved her
aesthetics. The patient was reviewed after
one month and a small part of the lower
denture was eased anteriorly coinciding with
an area of gingival hyperplasia.
The patient was last reviewed
nine months later and reported no problems
apart from a recurrence of BCC (Figure 5).
Overall, she was very satisfied with the
aesthetic and functional result and reported
an improved quality of life. However, she also
reported that her BCC has returned, and she
is awaiting a further course of chemotherapy.
Discussion
This case highlights the
difficulties in managing patients with
microstomia. Microstomia can cause
difficulties during every stage of prosthetic
construction. It was decided to use the bite
fork compound technique; an alternative
technique would have been to use sectional
trays to create a preliminary impression.
However, this technique poses the challenge
involved in relocating the sectional trays
outside the mouth.6
In severe cases of
microstomia, patients can struggle with
the relatively simple tasks of denture
insertion and removal. In this case, the
patient suffered from transient discomfort
when stretching her skin on insertion and
removal of impressions, registration blocks
and the final dentures.
This was a challenging
prosthodontic case, given that the smallest
stock impression tray was too large to
fit intra-orally. It was eventually decided
that the only option, aside from a split
tray technique, was to use the bite fork
innovatively from an articulator with
impression compound to construct a
unique preliminary impression tray which
was suitable for this patient. This worked
well and consideration of this technique is
recommended when a similar situation is
encountered.
After further consideration
of the patient’s unexplained multiple
BCC, perhaps this is a case of Gorlin-Goltz
syndrome.
Conclusion
With the challenges associated
with microstomia, it is important to use
resources already available innovatively to
treat these patients, and ultimately provide
satisfactory dentures. This technique is
both a practical and inexpensive solution,
attractive in modern dentistry as it may
improve both quality of patient care and
cost-effectiveness. We therefore suggest
that, in cases where small stock trays are
too large to fit in patients’mouths, this
compound and bite fork technique is
considered to construct special trays.
